Split unit and functional tests

[Tang Chen]

Now, Ironic is known as a project without functional tests. But actually, a part of unit tests in Ironic do start a server using pecan, using the same configuration as those in the real code. So they look more like functional tests, but they do fake many calls.

In one word, unit tests and functional tests in Ironic are now mixed. If we want to do better functional tests for Ironic, we should split them first.

I'm not saying we shouldn't or don't want to do this, but it's not useful having the bug around unless someone is interested in taking up this work.
