they all still used some odd side effects of the tree structure to
decided what record type they operated on, just move them over to the
new `ty` record.

There is a race upon reload, where it can happen that:
1. systemd forks off /bin/kill -HUP $MAINPID
2. Current instance forks off new one and notifies systemd with the
new MAINPID.
3. systemd sets new MAINPID.
4. systemd receives SIGCHLD for the kill process (which is the current
control process for the service) and reads the PID of the old
instance from the PID file, resetting MAINPID to the PID of the old
instance.
5. Old instance exits.
6. systemd receives SIGCHLD for the old instance, reads the PID of the
old instance from the PID file once more. systemd sees that the
MAINPID matches the child PID and considers the service exited.
7. systemd receivese notification from the new PID and is confused.
The service won't get active, because the notification wasn't
handled.
To fix it, update the PID file before sending the MAINPID
notification, similar to what a comment in systemd's
src/core/service.c suggests:
> /* Forking services may occasionally move to a new PID.
> * As long as they update the PID file before exiting the old
> * PID, they're fine. */
but for our Type=notify "before sending the notification" rather than
"before exiting", because otherwise, the mix-up in 4. could still
happen (although it might not actually be problematic without the
mix-up in 6., it still seems better to avoid).

without that one gets a "failed to lookup datastore X" in the log for
every datastore that is in read-only or offline maintenance mode,
even if they aren't scheduled for GC anyway.
Avoid that by first opening the datastore through a Lookup operation,
and only re-open it as Write op once we know that GC needs to get
scheduled for it.

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
https://docs.rust-embedded.org/book/static-guarantees/design-contracts.html

RDD update did not use lookup_datastore() and therefore bypassed
the maintenance mode checks. This adds the needed check directly.

while all statements here are technically true - adding all
virtualization improvements is not relevant for proxmox backup in most
cases.
The intel nic driver seems like a left-over from a time (pre PVE 5.1)
where the pve-kernel included the out-of-tree drivers.

this not only makes the action disable/hide checks simpler, but also
prepares the view a bit for the idea of adding a new API endpoint
that returns the whole datastore content tree as structured JSON so
that it can be directly loaded into a tree store.

Allow pulling all groups from a certain source namespace, and
possibly sub namespaces until max-depth, into a target namespace.
If any sub-namespaces get pulled, they will be mapped relatively from
the source parent namespace to the target parent namespace.
