both used the 'Display' trait of pbs_datastore::BackupDir, which is not
intended to be serialized anywhere. Instead, manually format the path
using the print_ns_and_snapshot helper, and conversely, parse with
'parse_ns_and_snapshot'. to be a bit safer, change the register_snapshot
signature to take a BackupNamespace and BackupDir instead of a string.

We decided to go this route because it'll most likely be
safer in the API as we need to explicitly add namespaces
support to the various API endpoints this way.
For example, 'pull' should have 2 namespaces: local and
remote, and the GroupFilter (which would otherwise contain
exactly *one* namespace parameter) needs to be applied for
both sides (to decide what to pull from the remote, and what
to *remove* locally as cleanup).
The *datastore* types still contain the namespace and have a
`.backup_ns()` getter.
Note that the datastore's `Display` implementations are no
longer safe to use as a deserializable string.
Additionally, some datastore based methods now have been
exposed via the BackupGroup/BackupDir types to avoid a
"round trip" in code.

used_datastores returned the 'target', but in the full_restore_worker,
we interpreted it as the source and searched for a mapping
(which we then locked)
since we cannot return a HashSet of Arc<T> (missing Hash trait on DataStore),
we have now a map of source -> target

And use the api-types for their contents.
These are supposed to be instances for a datastore, the pure
specifications are the ones in pbs_api_types which should be
preferred in crates like clients which do not need to deal
with the datastore directly.

in 'restore_archive', we reach that 'catalog.commit()' for
* every skipped snapshot (we already call 'commit_if_large' then before)
* every skipped chunk archive (no change in catalog since we do not read
the chunk archive in that case)
* after reading a catalog (no change in catalog)
in all other cases, we call 'commit_if_large' and return early,
meaning that the 'commit' there was executed too often and
unnecessary, so move it after the loop over the files, before
finishing the temporary database.

instead of having a public start/end_chunk_archive and register_chunks,
simply expose a 'register_chunk_archive' method since we always have
a list of chunks anywhere we want to add them

if an error occurs, the snapshot dirs will already be created, and we
do not clean them up (some might already be finished).
Warn the user that they are not cleaned up.

this makes it possible to only restore some snapshots from a tape media-set
instead of the whole. If the user selects only a small part, this will
probably be faster (and definitely uses less space on the target
datastores).
the user has to provide a list of snapshots to restore in the form of
'store:type/group/id'
e.g. 'mystore:ct/100/2021-01-01T00:00:00Z'
we achieve this by first restoring the index to a temp dir, retrieving
a list of chunks, and using the catalog, we generate a list of
media/files that we need to (partially) restore.
finally, we copy the snapshots to the correct dir in the datastore,
and clean up the temp dir

by checking the 'checked_chunks' before trying to write to disk
and by doing the existance check in the parallel handler. This way,
we do not have to check the existance of a chunk multiple times
(if multiple source datastores gets restored to the same target
datastore) and also we do not have to wait on the stat before reading
the next chunk.
We have to change the &WorkerTask to an Arc though, otherwise we
cannot log to the worker from the parallel handler

Split out a separate function scan_chunk_archive() for catalog restores.
Note: Required, because we need to optimize restore_chunk_archive() to
write datastore in separate threads (else thape drive will stop during restore)
when we get an error from the tape, we possibly want to ignore it,
i.e. when the file was incomplete, but we still want to error
out if the error came from e.g, the datastore, so we have to move
the error checking code to the 'next_chunk' call

by changing the 'store' parameter of the restore api call to a
list of mappings (or a single default datastore)
for example giving:
a=b,c=d,e
would restore
datastore 'a' from tape to local datastore 'b'
datastore 'c' from tape to local datastore 'e'
all other datastores to 'e'
this way, only a single datastore can also be restored, by only
giving a single mapping, e.g. 'a=b'
