* 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.

* added framework for unit testing against remote real rclone remotes,
added google drive backend
* added parallelism to blobtesting which revealed some races during
PutBlob with WebDAV.
Also introduced strongly typed content.ID and manifest.ID (instead of string)
This aligns identifiers across all layers of repository:
blob.ID
content.ID
object.ID
manifest.ID
This updates the terminology everywhere - blocks become blobs and
`storage.Storage` becomes `blob.Storage`.
Also introduced blob.ID which is a specialized string type, that's
different from CABS block ID.
Also renamed CLI subcommands from `kopia storage` to `kopia blob`.
While at it introduced `block.ErrBlockNotFound` and
`object.ErrObjectNotFound` that do not leak from lower layers.
