Summary:
This is a pretty straightforward IPA joining test. Since I
figured out how to set up a DHCP server for support_server,
let's do the same for the domain controller so we can simplify
these enrolment tests a bit.
We also extend the timeout on installing haveged on the server
a bit (2 minutes is a bit low when it hits a slow metadata
download), and drop an unnecessary clone_host_file from the
cockpit join test (it was only there for testing and the next
operation immediately overwrites it).
Test Plan:
Do a full server DVD test run, check the new test
works and none of the others broke.
