Now that we have a function that generates string list for given enum, let's use that instead of open coding it. Note, after this there are still some 'candidates' left (e.g, virshNetworkEventNameCompleter(), or virshNetworkUpdateCommandCompleter()). These are not converted because either they don't have a convenient int2str function or they don't start from the very beginning of the enum.
