* feat: persisting retention options in repository blob
- plumb retention parameters through wrapped storage
- generalize aes encryption mechanism
- rewrite the retention blob on password change
- do not write retention blob when empty
* handle retention-blob not-found failures
* cli params to set retention modes on repository create
* enable versioned map mock storage with retention settings
* adding unit tests
* write format and retention blob with retention settings if available
* rename certain functions and constants specific to format blob
* delete retention cache on password-change
* fix: replace SetTime() api call with TouchBlob()
* Update repo/repository_test.go

* sharded: plumbed through blob.PutOptions
* blob: removed blob.Storage.SetTime() method
This was only used for `kopia repo sync-to` and got replaced with
an equivalent blob.PutOptions.SetTime, which wehn set to non-zero time
will attempt to set the modification time on a file.
Since some providers don't support changing modification time, we
are able to emulate it using per-blob metadata (on B2, Azure and GCS),
sadly S3 is still unsupported, because it does not support returning
metadata in list results.
Also added PutOptions.GetTime, which when set to not nil, will
populate the provided variable with actual time that got assigned
to the blob.
Added tests that verify that each provider supports GetTime
and SetTime according to this spec.
* blob: additional test coverage for filesystem storage
* blob: added PutBlobAndGetMetadata() helper and used where appropriate
* fixed test failures
* pr feedback
* Update repo/blob/azure/azure_storage.go
