[PATCH manager v3 03/18] ui: form: add filtered KVComboBox

[Dominik Csapak <d.csapak@proxmox.com>]

this makes it easier to have the same KVComboBox, but for different
configurations, depending on a single 'category' value. This is useful
for having the same KVComboBox in different categories, such as the cpu
architecture, for e.g. the scsi hw or bios selector, which need different
values for different architectures.

Instead of implementing the logic for each KVComboBox, abstract it away,
so we can reuse the code and have consistent behavior here.
