groups collection item streaming is missing
recoverable errors, and is only logging at this time. This may be causing backups to succeed even
when errors should cause a failure.

Expand BaseCollection to have a helper function that returns the Category. Attempts to source from the FullPath and falls back to the PreviousPath if necessary.

Implement lazy data fetch for Exchange items.
Use a new collection type to clearly denote
when items can be lazily fetched vs. requiring
eager fetch
**This PR changes how the read bytes stat is
updated.** Lazily fetched items will not
update the read bytes stat. This stat doesn't
appear to be used anywhere at the moment
For items that are deleted between the time
enumeration takes place and the time the data
for them needs fetched, the corso will:
* return an empty reader for the item
* not add the item to backup details
* delete the (empty) item from kopia on the
next backup
Manually tested deleting an item between
enumeration and data fetch

Will be making another collection type based
on the same skeleton.
No logic changes in this PR, just naming.

No real changes to API or internal structure,
but pull out more generic functionality like
getting the path/location info for an
exchange collection into a separate struct
and factor out some soon-to-be common
functions

Update the API for Item.Info to return an error.
This can then be leveraged to add lazy readers
to exchange backups
See #2023 for more info on how to add lazy
readers to exchange

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.
