admin/datastore reads linearly only, so no need for cache (capacity of 1
basically means no cache except for the currently active chunk).
mount can do random access too, so cache last 8 chunks for possibly a
mild performance improvement.

when we remove a datastore via api/cli, the proxy
has sometimes leftover references to that datastore in its
DATASTORE_MAP which includes an open filehandle on the
'.lock' file
this prevents unmounting/exporting the datastore even after removal,
only a reload/restart of the proxy did help
add a command to our command socket, which removes all non
configured datastores from the map, dropping the open filehandle

This can happen if the underlying storage failed, in which case we do
not want to fail the whole API call, as it should report the status
of all datastores. So rather add the error inline to the related
store entry and continue.
Allows to nicely visualize those stores in the gui.

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

when a user updates a job schedule, we want to save that point in time
to calculate future runs, otherwise when a user updates a schedule to
a time that would have been between the last run and 'now' the
schedule is triggered instantly
for example:
schedule 08:00
last run today 08:00
now it is 12:00
before this patch:
update schedule to 11:00
-> triggered instantly since we calculate from 08:00
after this patch:
update schedule to 11:00
-> triggered tomorrow 11:00 since we calculate from today 12:00
the change in the enum type is ok, since by default serde does not
error on unknown fields and the new field is optional

Add a watchdog that will automatically shut down the VM after 10

Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
Implements the base of a small daemon to run within a file-restore VM.
The binary spawns an API server on a virtio-vsock socket, listening for
connections from the host. This happens mostly manually via the standard
Unix socket API, since tokio/hyper do not have support for vsock built
in. Once we have the accept'ed file descriptor, we can create a
UnixStream and use our tower service implementation for that.
The binary is deliberately not installed in the usual $PATH location,
since it shouldn't be executed on the host by a user anyway.
For now, only the API calls 'status' and 'stop' are implemented, to
demonstrate and test proxmox::api functionality.
Authorization is provided via a custom ApiAuth only checking a header
value against a static /ticket file.
Since the REST server implementation uses the log!() macro, we can
redirect its output to stdout by registering env_logger as the logging
target. env_logger is already in our dependency tree via zstd/bindgen.

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'

- change pool lock name to ".pool-{name}"
