this series improves the behaviour of the file-restore when some mount
operations take longer than the 30 second pveproxy timeout

some of the previous version was already applied (pbs + gui) so only
the pve part is still missing

i changed the way we return the error a bit from my previous (and
already applied) attempt, namely i couple how we return the error
on the 'output-format' instead of a seperate 'json-error'

while this is technically a change in behaviour, this is imho ok because:
* setting 'output-format' to json(-pretty) did not format the error,
  so a tool would have to cope with the pure text
* AFAIK we don't have the same guarantees for the cli as for the api
* it's a much better interface than before

but since this changed, and the 'json-error' was already applied,
the dependencies go as follows:

pve-storage depends on the new proxmox-backup-file-restore/pve-common
to work properly, but it's not broken with the current versions
proxmox-backup breaks the current pve-storage (so that we must bump and
add a 'breaks <<' probably)

the gui should already handle the new code, so that is fine either way

changes from v2:
* couple the error format to 'ouput-format' instead of 'json-error'
* remove 'error' property from 'error json object' (was redundant)
* always expect an error when we get an object and always treat
  it as ok when we get a list

changes from v1:
* rebased on master
* moved the json-error and timeout directly into pve-common (hardcoded)
  since there is only one usage of that function
