Truly handle mailmap entries for all combinations.

Bug: 994957

Mailmap might contain mapping with full name. This commit fixes
it to handle these combinations:
  Foo ZZ <email@foo.com> Bar YY <email@bar.com>
  Foo <email@foo.com> Bar <email@bar.com>
  <email@foo.com> <email@bar.com>

This is inline with mailmap convention described here:
  http://man.github.com/git/git-shortlog.html

* keystone/openstack/common/setup.py
  parse_mailmap(): Pull out canonical and alias email addresses.

* keystone/tests/test_setup.py
  New test script to cover various combinations in mailmap.
