[pve-devel] [PATCH container] setup: centos: separate dns-search list with semicolons

[Maximiliano Sandoval]

This is a followup of 6e08c550.

Unlike the previous commit, the key `dns-search` is not documented as
part of the manual page `nm-settings-keyfile(5)`. Here we rely solely on
lists being generally semicolon-separated in NetworkManager and the test
case `Test_Wireless_Connection` [1, 2, 3].
