Split out nsx_user/pass to nsxv3 section

The default password for nsx-t changed from admin to default which is
different than the default for nsx-mh. This patch splits out the nsx-t
user/pass config options to it's own section so the defaults are correct.
In addition these should be in their own config section anyways.
