This reverts commit acf50c44.

This reverts commit ed80381b, reversing
changes made to 205cb8b3.

This includes:
* Ability to specify number of processes to run bok-choy tests in
* A forked nose commit to get the multiprocess plugin's logging to work
* A different plugin (xunitmp) must be used for pulling together xunit results

This works by:
* Starting the various servers that are needed for the acceptance test environment
* Running the tests themselves in multiprocess mode

* Fix paver violations to stablize edx-lint update
* Parens, Line2Long
* Fix missing docstrings
* Fix PEP8 issues
* Address PR feedback (thanks @nedbat!)

This would allow a user to set up and run servers, with an open prompt for killing
them. Likewise a user could open a different terminal session and run tests only.

How-to:
* At a terminal/ssh session, start bok-choy servers with
    `paver test_bokchoy --serversonly`
    (or, if you've already run collectstatic on your system:
    `paver test_bokchoy --serversonly --fasttest`)
* When the above is running, you can now open a separate terminal/ssh session
and run:
    `paver test_bokchoy -t my_tests --testsonly`

Keep in mind, the 'testsonly' flag does no setup. There is some minimal teardown; however,
such as clearing mongo and flushing the lms database. (Some tests have non-unique identifiers
and could not be run more than once.)

This allows developers to pass the `--pdb` flag to paver test commands,
and that flag will be proxied to the `nosetests` command. It's useful
for debugging purposes.
