[PATCH datacenter-manager v2] ui: auto-installer: filter by country name and code

[Christian Ebner <c.ebner@proxmox.com>]

The country filed for answer files expects a 2 character country
code as input, while showing the full country name for items. The
filter therefore currently applies to country codes only, not
matching on country (common) names.

Filter based on both, matching name or country code instead.

Changes since version 1 (thanks @Shannon):
- match country name by containing string instead of starting with
  query string.
