Introduced in v5.10.0-449-gcf44ec5577 it used virshCommaStringListComplete() to generate list of options. But this is not correct because the '--source' argument of the 'domifaddr' doesn't accept a string list (for instance "arp,agent,lease") rather than a single string. Therefore, the completer must return these strings separately and thus must refrain from using virshCommaStringListComplete(). At the same time, now that we have strings we need declared as an enum we can use TypeToString() instead of copying strings.
