Quite often users choose wrong type of trust on Active Directory side
when setting up a trust to freeIPA. The trust type supported by freeIPA
is just a normal forest trust to another Active Directory. However,
some people follow old internet recipes that force using a trust to MIT
Kerberos realm.
This is a wrong type of trust. Unfortunately, when someone used MIT
Kerberos realm trust, there is no way to programmatically remote the
trust from freeIPA side. As result, we have to detect such situation and
report an error.
To do proper reporting, we need reuse some constants and trust type
names we use in IPA CLI/Web UI. These common components were moved to
a separate ipaserver/dcerpc_common.py module that is imported by both
ipaserver/plugins/trust.py and ipaserver/dcerpc.py.
