Description of problem:
When using fedpkg to submit a tag request, it first fails with

  Could not execute tagrequest: 'Commands' object has no attribute 'get'

which is due to the first line of the body of the tagrequest method definition in cli.py:

  self.cmd.tracbaseurl = self.cmd.get('fedpkg', 'tracbaseurl', raw=True)

After editing the file to manually set tracbaseurl to the value in fedpkg.conf, it then fails with:

  Could not request a tag release: 'Commands' object has no attribute 'override'

as soon as it tries processing the description (whether description text is passed interactively or through --desc)

Version-Release number of selected component (if applicable):
fedpkg-1.14-1.fc20.noarch
pyrpkg-1.19-2.fc20.noarch

How reproducible:
Always (also on RHEL 6)

Steps to Reproduce:
1. Clone a Fedora package with fedpkg
2. cd into the package directory
3. fedpkg tag-request

Actual results:
Error described above

Expected results:
Should just work
