by adding a new parameter 'namespaces', which contains a mapping
for a namespace like this:
store=datastore,source=foo,target=bar,max-depth=2
if source or target are omitted the root namespace is used for its value
this mapping can be given several times (on the cli) or as an array (via
api) to have mappings for multiple datastores
if a specific snapshot list is given simultaneously, the given snapshots
will be restored according to this mapping, or to the source namespace
if no mapping was found.
to do this, we reutilize the restore_list_worker, but change it so that
it does not hold a lock for the duration of the restore, but fails
if the snapshot does exist at the end. also the snapshot will now
be temporarily restored into the target datastore into the
'.tmp/<media-set-uuid>' folder.

We sometimes need to do some in-memory only stuff, e.g., to check if
GC is already running for a datastore, which is a try_lock on a mutex
that is in-memory.
Actually the whole thing would be nicer if we could guarantee to hold
the correct contract statically, e.g., like

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.

The idea is to have namespaces in a datastore to allow grouping and
namespacing backups from different (but similar trusted) sources,
e.g., different PVE clusters, geo sites, use-cases or company
service-branches, without separating the underlying
deduplication domain and thus blowing up data and (GC/verify)
resource usage.
To avoid namespace ID clashes with anything existing or future
usecases use a intermediate `ns` level on *each* depth.
The current implementation treats that as internal and thus hides
that fact from the API, iow., the namespace path the users passes
along or gets returned won't include the `ns` level, they do not
matter there at all.
The max-depth of 8 is chosen with the following in mind:
- assume that end-users already are in a deeper level of a hierarchy,
most often they'll start at level one or two, as the higher ones
are used by the seller/admin to namespace different users/groups,
so lower than four would be very limiting for a lot of target use
cases
- all the more, a PBS could be used as huge second level archive in a
big company, so one could imagine a namespace structure like:
/<state>/<intra-state-location>/<datacenter>/<company-branch>/<workload-type>/<service-type>/
e.g.: /us/east-coast/dc12345/financial/report-storage/cassandra/
that's six levels that one can imagine for a reasonable use-case,
leave some room for the ones harder to imagine ;-)
- on the other hand, we do not want to allow unlimited levels as we
have request parameter limits and deep nesting can create other
issues as well (e.g., stack exhaustion), so doubling the minimum
level of 4 (1st point) we got room to breath even for the
more odd (or huge) use cases (2nd point)
- a per-level length of 32 (-1 due to separator) is enough to use
telling names, making lives of users and admin simpler, but not
blowing up parameter total length with the max depth of 8
- 8 * 32 = 256 which is nice buffer size
Much thanks for Wolfgang for all the great work on the type
implementation and assisting greatly with the design.

Returning the GC status was dropped by mistake in commit 762f7d15
("datastore status: factor out api type DataStoreStatusListItem")
As this is considered a breaking change which we also felt, due to
the gc-status being used in the web interface for the datastore
overview list (not the dashboard), re add it.
