Exclude preview backups when looking for bases (#4593)
Add a comment and test ensuring preview backups are excluded during
base selection as expected. It's still not possible to make a
backup tagged with the preview tag right now

Minor refactor for checking backup type when finding bases (#4592)
Use the new helper function to get the backup type and rewrite logic
to streamline checks/actions on the backup type

Hoists a check on the backup's snapshot ID higher in the code and
adds a test case for that

Refactor base finder tests to be more compact and easier to make (#4586)
These tests were originally written before we checked backup
models when searching for bases. This refactor updates the
tests with helper functions that create self-consistent
backup and manifest models. Overall this pattern makes it
easier to declare the data the test uses, easier to read
test data, and makes the tests more compact

Reviewing this PR by commit may be easier

Cleanup API for BackupBases (#4471)
Update the BackupBases API to return BackupBase
structs that contain both the snapshot and backup
model instead of having separate functions for
each. Minor logic updates to accommodate these
changes

This PR also updates tests and mock code for the
new API

Move Reasoner implementation to identity package (#4468)
Move the Reasoner implementation from the kopia package to the identity

Track assist bases and merge bases separately (#4181)
Do a few things to separate merge and assist bases
* use distinct sets for each base type
* make another function to return all base snapshots to pass to kopia assisted incrementals

Fix cases where we had a trailing comma (#4208)
Not sure if we wanna merge it as it might generate way too many conflicts, but this should help us add a linter in CI. If we are good, I'll add something that can do lints for this in a follow up PR.

Super hacky, but this fix was created using `while true ; do tree-grepper -q go '(argument_list "," @nope .)' | tail -n1| awk -F: "{print \$1,\"+\"\$2\" -c ':norm \$xJZZ'\"}" | xargs vim ; done`.

Return assist backup models during base selection process (#3907)
<!-- 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.

Create an interface and implementation for Reason struct (#3868)
Intermediate step to a few different goals including
* moving interface definitions to better locations while avoid cycles
* adding a flag to disable kopia-assisted incrementals

Create an interface and implementation for the existing Reason
struct. The goal is to set stuff up so that eventually the kopia
package can ask the struct for the subtree path to work with
when merging the hierarchy instead of having the backup operation
pass that information in

Code changes are mostly just turning stuff into a struct and
fixing up compile errors. Some functions have been excluded from
the struct (i.e. `Key`) and made into functions in the kopia
package itself

as it does result in looking up backup

new way of finding bases out and then we
can go back and smooth things over when
we have the chance
