Shuffle around some logic for details merging so that
we always attempt to extract a LocationRef from the
backup base entry that's currently being examined.
A LocationRef should always be available from either
the LocationRef field in the details entry (newer
backups) or by extracting it from the RepoRef (older
backups)
Manually tested incremental backups for exchange in
the following scenarios:
1. v0.3.0 backup (calendars use IDs in RepoRef) ->
incremental with this patch -> incremental with
this patch
1. v0.2.0 backup (exchange uses folder names in
RepoRef) -> incremental with this patch ->
incremental with this patch
The above tests should cover the cases where:
* base backup details don't have LocationRef for
exchange items
* base backup details have LocationRef for exchange
items

Adds the boilerplate for groups backup collection processing. Not necessarily functional at this time, due to missing dependencies and consts that aren't yet in the branch. Thus the lack of tests. It's just good enough to keep progress rolling forward.

This PR optimizes memory & cache refresh time for URL cache. The cache only makes use of a small subset of drive item properties, namely ID, deleted, file, folder, content download URL. We have found that reducing the number of query properties has a sizable impact on corso mem usage. This is especially relevant for large scale backups.
See below graph for a comparison between original delta queries & mod. Note that this is with corso instrumentations to show comparisons side by side in the same run.
- Reading this graph
- We are doing 3 orig delta queries followed right after by 3 mod. Vertical lines are delta query spans.
Originally, this investigation was done to improve mem usage for scale backups. But we also found that url cache delta query time drops by 22% with this PR. This is because we are now transferring & processing fewer bytes.

Starting code for removing item data snapshots,
backups, and backup details that have been
orphaned. Data can become orphaned through either
incomplete backup delete operations (older
corso versions) or because backups didn't
complete successfully
This code doesn't cover all cases (see TODOs in
PR) but gets a lot of the boiler-plate that will
be required. Future PRs will build on what's in
here to close the gaps
This code is not wired into any corso operations
so it cannot be run outside of unit tests

GET permissions fails if the item doesn't exist. We are hitting sanity test failures due to a race condition between test run & purge scripts.
`getting item metadata: getting item metadata: error status code received from the API: Item not found:`
Fix here is to ignore GET permissions failure if it returns not found. This is safe to do here, since the graph call for permissions [looks up the item by id](https://github.com/alcionai/corso/blob/main/src/pkg/services/m365/api/drive.go#L254C17-L254C17), and not the permissions by id. Hence, we can safely assume that the item that this permission is tied to has been deleted.

This PR adds changes to persist backup models for assist backups. Primary reason for doing this is to ensure we don't lose corso extension data(deets) for items which were downloaded and processed by kopia during this backup op.
Note: This is 1/n PRs, and will not be merged into main until all n are reviewed, given we are touching state here.
**Changes in this PR:**
1. Error handling changes to ensure assist backups get persisted
2. Introduce tags for assist/merge backups. These tags will be used for filtering during base selection process.
3. Don't persist backups if they are not assist backup, and they have non zero errors.
4. Remove `LabelForceNoBackupCreation` criteria for not persisting a backup. More details are in [PR comment](https://github.com/alcionai/corso/pull/3905/files#r1278030140).
5. Switch kopia failure from non-recoverable to recoverable. More details are in [PR comment](https://github.com/alcionai/corso/pull/3905/files#r1278019992).
**What are assist backups?**
Below conditions must be true for a backup operation to qualify as an assist backup.
1. new deets were produced during this backup operation
2. we have a valid snapshot ID
3. we don't have any non-recoverable errors
4. we have recoverable errors
**A merge backup satisfies the following conditions:**
1. Is not an assist backup
2. No primary or recoverable errors occurred during the backup operation.
Tests will be added in later PRs.

Update backup details merge logic to use assist
backup bases. As the modTime check is already in
DetailsMergeInfoer there's not much else to do
here besides wiring things up
Overall, this solution is an alternative to the
previous one. It works by placing all cached
items in the DetailsMergeInfoer instead of adding
them to details (assuming they had a details
entry)
During details merging, we can cycle through
all bases once and track only the items we've
added to details (so we don't duplicate things).
This works because we know precisely which items
we should be looking for
ModTime comparisons in the DetailsMergeInfoer
ensure we get the proper version of each item
details
**Note:** This requires a minor patch to how
we determine if it's safe to persist a backup
model because now backups won't produce details
entries for cached items until `mergeDetails`
runs

<!-- PR description-->
This PR adds support for selecting assist backup models. The intent here is to use the assist backups during merge details process.
Changelist:
1. Assist bases now have a requirement to have a) an associated assist backup model b) details ssid. Please see [this code comment](https://github.com/alcionai/corso/pull/3907/files#diff-f9b6b7ab52c8e1148147909fd071d9b80b816d072203d8e9d2fa34ab93185db1R286) for more.
2. Any incomplete assist bases or assist bases not matching 1) are now discarded, i.e. they are not fed to kopia for kopia assisted incrementals. The impact here is that files cached by kopia might be now redownloaded if the backup failed without qualifying for an assist backup.
Unit tests added.

Add modTime as one of the things that the
DetailsMergeInfoer knows how to check against,
wire it into details merging, and populate it
during item upload
This will help merge assist backup base items
by allowing us to do a direct comparison on
modTimes if we add them to the
DetailsMergeInfoer during upload

Getting all folders was originally for the purge script. We've now transitioned to a powershell-based purge script making this code unused.
Tests have coverage for a little more beyond just getting all folders but other code should either have tests for similar functionality or doesn't need it.

Create a wrapper for `io.ReadCloser`s that are fetched
from the network. This wrapper allows attempting to
restart a connection if it returns an `io.ECONNRESET`
error (this can be adjusted fairly easily)
Automatically seek the reader obtained from the retry
to the proper place in the stream so that there's no
gap or repeats in the returned data. This is done
either by reading and discarding bytes or by
requesting a range of bytes from the source

replaces the restore cache maps with threadsafe maps.
Onedrive restores would rarely fail due to concurrent
map writes against the restore cache maps. This change
should protect against failure in those conditions.
