To achieve this, start a worker task and use our generic api client
to start the tasks on the relevant nodes. The client always points
to 'localhost' so we let the pveproxy worry about the proxying etc.
We reuse some logic from the startall/stopall/etc. calls, like getting
the ordered guest info list. For that to work, we must convert some of
the private subs into proper subs. We also fix handling loading configs
from other nodes.
In each worker, for each task, we check if the target is in the desired
state (e.g. stopped when wanting to start, etc.). If that is the case,
start the task and put the UPID in a queue to check. This is done until
the parallel count is at 'max_workers', at which point we wait until at
least one task is finished before starting the next one.
Failures (e.g. task errors or failure to fetch the tasks) are printed,
and the vmid is saved and they're collectively printed at the end for
convenience.
Special handling is required for checking the permissions for suspend:
We have to load the config of the VM and find the target state storage.
We can then check the privileges for that storage.
Further improvements can be:
* filters (I'd prefer starting out with front end filters)
* failure mode resolution (I'd wait until someone requests that)
* token handling (probably not necessary since we do check the
permissions upfront for the correct token.)

changes from v1:
* rebased on master (perltidy changes)
* added missing suspend to index
* refactored more functionality to be reused
