adds item collision handling to exchange restores. Currently an incomplete implementation; the replace setting will skip the restore altogether (no-op) as a first pass. The next PR will finish out the replace behavior.

The current rate limit default maximizes the number of calls we can make in the first 10 minutes, but the larger initial bucket size means we have to drop the per-second token burst. As a result, any process longer than 10 minutes is going to see unnecessary rate limiting by ~100 calls per minute.
This change swaps the large initial bucket for a smaller one, and a larger token burst to increase throughput across long runtimes.

<!-- PR description-->
Currently we do full delta enumeration during cache refresh events. It has some disadvantages as listed in https://github.com/alcionai/corso/issues/3482 .
This PR allows us to instantiate the URL cache with a delta token. This delta token is identical to the one used during onedrive item enumeration.
The URL cache might do multiple delta queries(once every hour) using the same delta token.

Changes:
* Attach URL cache to a collection only if it's parent drive has < 300k items. Higher item count reduces the ROI of using cache, and can even degrade performance in severe cases. We will stick to per item GETs for those scenarios, until we figure out a longer term solution.

Some events in have a empty repoID. This could be because of multiple
config files used. And new config files might have repoID missing.
Solution- Fetch repoID from Kopia is not found locally in the config
file.
Note: Since the Corso Start event happens before we connect to Kopia, it
might have repoID missing if the config file is used for the first time.
All the consecutive events will have correct values. Corso start event
will start populating correct values if the config file is used once.

This last step in the cleanup has two goals: first to minimize the number of arbitrarily named and located files so that code is better condensed and co-located. This is all just file renaming and a minor amount of code copy-pasting.
The second is to create a centralized package to own the ColInfo type structs that we use to both stub out test data, and also generate factory data for cmds. The current ownership is haphazard, and while this movement is a little more condensed, it's still jumping through some weird hoops to get things to work. Treat it as one good step forward, and we'll have to return to polish it another time. At least it'll be separated from the m365 folder at large this way, and more easily identified as supporting design rather than production usage.

Corso detects malware in a few places for OD/SP.
1. During item enumeration, using [malware property](https://learn.microsoft.com/en-us/graph/api/resources/driveitem?view=graph-rest-1.0#properties) which is set by graph - [code](ed47c134b0/src/internal/connector/onedrive/collections.go (L658))
2. During item fetch using download URL - [code](ed47c134b0/src/internal/connector/onedrive/item.go (LL53C18-L53C18))
- Graph seems to return 403 with `{"error":{"code":"malwareDetected","message":"Malware detected"}}`. Tested with eicar.
3. By analyzing http response headers in `IsMalwareResp` Don't see these headers documented by graph. This is for [sharepoint protocol compatibility](https://learn.microsoft.com/en-us/openspecs/sharepoint_protocols/ms-wdvmoduu/6fa6d4a9-ac18-4cd7-b696-8a3b14a98291) it seems.
4. By analyzing response body in `IsMalwareResp` . We check for malwareDetected string inside http response body.
We are accidentally dumping entire file ( http response dump) while checking for malware in 4. This is leading to high mem utilization/OOMs, especially while processing very large files.
I don't think we need 4 at all. If graph is the entity which detects malware, I think we will never get past 2. This PR removes item 4.

Don't read all the files that we need to restore, just the collections in the beginning. The rest of them are read using Fetch on demand when they will be restored.

refactors exchange restore from near-duplicate per-category functions and switch-based process trees with interfaces.
At the top of restoring all collections, each category creates a categoryRestoreHandler to supply the necessary restore behavior. The appropriate handler gets passed in to the collection restore, and all restore code after that takes a single path using a common restore interface to switch between categorical behavior.

Data should be cleaned up by purge script when it runs so there's no need to risk test failures by trying to clean it up at the end of the test

Take the new base finder code, wrap it in
a thin wrapper and use it in place of the
previous way of finding base snapshots
This solution is not focused on efficiency
as it does result in looking up backup
models multiple times. It's more to get the
new way of finding bases out and then we
can go back and smooth things over when
we have the chance

<!-- PR description-->
Currently the backup output show,
- total backup size - size of files + size of metafiles
- no of files - no of files + no of metafile
With this change the output of backup command shows size of only files and count include only file count.
NOTE: all current three services results will be impacted here.

If a user does not have a service(like exchange) enabled- don't throw an error but just skip that user and move forward with other backups.

Add a new set of functions to find
bases for incremental backups. The
new set of functions return
* set of backup models and the reasons for selecting each
* set of snapshots to merge and the reasons for selecting each
* set of snapshots for kopia-assisted incrementals and reasons for selecting each
New code is not wired into existing
system so no behavioral changes are
expected

Searching for new bases is mostly kopia-specific but is going to require the store interface. With the way packages and interfaces are currently laid out it makes it impossible to easily get the interface added to the inject package without a cycle.
This moves functions that the kopia package provides into a subpackage of the kopia package that other things can then import
This change only moves code. No logic is updated

This PR introduces an URL cache for onedrive items. Integration with code and additional unit/integration tests will be added in follow up PRs to keep this PR short.
Why do we need an URL cache?
* This is a perf improvement for long running backups.
* If the time difference between download URL fetch and content download is > 1 hour, the download will fail with a `401: Unauthorized` error. This is because JWT tokens attached with the download URLs are short lived (1 hour).
* Currently we refresh download URLs after `401` with a per item `GET` . This should be optimized because it's an extra round trip for every item (to get the 401 and then renew).
How does URL cache help?
* URL cache will do a full delta re-enumeration when we hit a 401. It will be cheaper (in terms of Graph requests/tokens) vs calling GetItem for everything left.
* It relies on lazy refresh. The URLs will only be refreshed once we hit a 401 and the client expliclty requests the cache for the download URL. Any following 401s will be served from the cache.
*

normalizes exchange api naming and client usage.
Also moves serialization and transformation to and from graph client objects out of graph/support and into the api. Some parts of graph/support have been moved into conn/ exchange instead, since they're more oriented around certain forms of object consumption rather than broad object serialization.
Except for different uses of api client graph servicers, all changes are movement/renaming.
