Improve the VirtualFull run job

[tikoflano]

Based on this #508 (comment)

Now you can select a NextPool value for your VirtualFull Backup, Copy or Migrate job. It considers this:

• If the Type is Backup:

  • If the selected Level is other than VirtualFull, the Next Pool field will be hidden and empty.
  • If the selected Level is VirtualFull, the Next Pool field will shown and populated with the Next Pool of the currently selected pool if it is defined, empty otherwise.
  • If the selected Pool changes and the Level is VirtualFull, the Next Pool field will be updated to the next pool for the recently selected pool if it is defined, keep the one currently selected otherwise.
  • If the selected Pool changes and the Level is not VirtualFull, it does nothing.

• If the Type is Copy or Migrate:

  • If the selected Pool changes, the Next Pool field will be updated to the next pool for the recently selected pool if it is defined, keep the one currently selected otherwise.

Thank you for the PR. Following are a few change requests.

• Please drop the merge message 56c16f9.

• Please combine all commits into one here and change the commit message subject to something like "webui: add next pool selection to custom job run form". Also put in something like your first PR comment in the commit description.

Other than that it seems good. Going to have a second look after cleanup is done.
