These were found using https://github.com/timakin/bodyclose. Not adding it as a linter for now as it was producing false positive(I think) on OneDrive item. The close was happening in a9918d2f78/src/internal/kopia/upload.go (L68) instead of right alongside it which might be why it got thrown off.

Now that the rate limiter is split by service, we can further split by per-query token consumption. Two primary service cases exist: all exchange queries assume to cost a single token (for now). Drive-service queries are split between permissions (5), default cost (2), and single-item or delta gets (1).

Handle 409, `ErrorFolderExists` error in restore path while creating destination calendar. We need to fix this for all m365 services. This PR is focused on calendar only.
Context:
`CreateCalendar()` may fail with ErrorFolderExists under certain error conditions. For e.g. consider below scenario.
1. `CreateCalendar()` does a POST to graph to create restore destination calendar but this fails with 5xx.
2. It's possible that step 1 may have left some dirty state in graph. For e.g. it's possible that the destination folder in step 1 was actually created, but 5xx was returned due to other reasons.
3. So when we reattempt POST in such a scenario, we sometimes observe ErrorFolderExists error .
4. Corso should be resilient to such errors. To fix this, when we encounter such an error, we will do a GET to fetch the restore destination folder and add it to folder cache.

The kiota compressor middleware will attempt to compress the request body. In the event that we have a corso-middleware- retriable response (eg: status 500), we need to reset the seek position of the req.Body, similar to how graph api does in their retry handler, or else the re-run of the compressor will already have read the full req.Body and the retried call will have a zero len body.

This helps ensure we have some set of things we can assume about

They have a valid snapshot ID for data
They have a valid snapshot ID for backup details
Eventually, this will allow us to say that backups using a base that
