[PATCH container] networkedit: fix #4911: changed primaryfield to proxmoxtextfield to allow empty bond-primary

[Lukas Sichert <l.sichert@proxmox.com>]

Currently, when creating an active-backup bond, it is not possible to leave the primary-bond field blank, even though this value is optional in the backend.
If no value is currently set in the frontend, it sends the value '' to the backend. There, it is interpreted as the name of an interface, which is incorrect, and therefore the error 'bond-primary: invalid format - invalid network interface name '' ' is displayed.
Changing the field type to 'proxmoxtextfield' will prevent the empty string from being sent due to the way we submit the data and make it therefore possible to not set any value in the frontend.
Addtionally, the deleteEmpty flag is set, so that devices, that were unset, will be deleted by the backend.
