feat: add integrated nice and ionice options for docker (#5448)
The intended usage here is to basically kick restic as a background
"do it, but don't bother my normal load" process.

This allows passing the following environment variables in to
influence scheduling:

- NICE: usual CPU nice.  Defaults to 0.  This requires CAP_SYS_NICE
  to set a negative nice (IE, prioritize).
- IONICE_CLASS: usual ionice class.  Note that setting realtime
  requires CAP_SYS_ADMIN.  Also note the actual ionice default
  is "none".
- IONICE_PRIORITY: set the priority within the given class.  Ignored
  if no class is specified due to class default of "no scheduler".
