[PATCH pve-manager v2 3/4] ui: backup: add error behavior and retry options

[Jakob Klocker <j.klocker@proxmox.com>]

Expose the `error-behavior` and `max-retries` vzdump parameters in the
scheduled datacenter backup and in the manual backup window.

When creating a new backup job or starting a manual backup, the UI
defaults to `retry` with a maximum of 5 retries.

The manual backup window only offers `retry` and `ignore`, since it
backs up a single guest, where `retry` and `retry-immediately` behave
the same. The width of the scheduled backup job window is increased
from 720 to 750 pixels so the new fields fit without cutting off their
labels.
