[PATCH manager 1/2] fix #6516: api: backup jobs: limit the job ID length on creation

[Michal Fox <me@dualfroz.com>]

All backup job API calls that take an existing job ID use the
'pve-backup-jobid' option, which is limited to 50 characters. The
create call uses its own 'id' parameter without that limit, so a longer
ID can be created, but the job can then neither be read, updated nor
deleted through the API or the web UI, and has to be removed from
jobs.cfg by hand.

Apply the same limit when creating the job.
