ipaclient.plugins.dns: Cast DNS name to unicode
cmd.api.Command.dnsrecord_split_parts expects name to be unicode
string and instead gets ascii. It leads to an error:
ipa: ERROR: invalid 'name': must be Unicode text
This commit's change is casting name's type to unicode so
'ipa dnsrecord-mod' will not fail with error above.
