Modify userinfo output to indicate when domain defaults are displayed
When Account instances reference NULL tid/qid/ssid, the data must come from
the associated domain, and this should be indicated. For transport and
services, this is easy to do as the string passed in the info dict can simply
be modified. For quotalimit, however, another method must be used due to the
CLI-side formatting.
All approaches use a common formatter outsourced to the common.py file.
