Move the Reasoner implementation from the kopia package to the identity
package. This will help avoid import cycles if we want to start
persisting Reason information in the backup model.

Add or update tests to ensure garbage collection works (or at least
behaves reasonably and in a known fashion) if:
* the youngest assist base has a merge base older than it
* there's a legacy backup model merge base younger than the assist
base
* there's legacy and current backup model merge bases younger than the
assist base

Do a bit better job checking assist bases for
garbage collection by considering whether
there's a newer merge base already

Add helper functions and tests that find
old assist bases and add them to the set
of backups to garbage collect. This
allows us to remove backups that aren't
displayed to the user because they had
some errors during them
The more recent assist backups can still
be used for incremental backups so we
don't want to garbage collect all of
them
This still does not wire this code into
any existing corso function, just adds
additional cleanup logic

Switch to using functions that always
return a new instance of the struct
in question. Upcoming tests were
having issues with state carrying
over between individual tests.

Exclude models that have been created within the
buffer period from garbage collection/orphaned
checks so that we don't accidentally delete
models for backups that are running concurrently
with the garbage collection task

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
