Remove times.dbm file for each tox run

[Peter Stachowski]

If you run the py27 tox tests then attempt to run the py34 tests, the
following error will occur:

    running testr
    running=OS_STDOUT_CAPTURE=${OS_STDOUT_CAPTURE:-1} \
    OS_STDERR_CAPTURE=${OS_STDERR_CAPTURE:-1} \
    OS_TEST_TIMEOUT=${OS_TEST_TIMEOUT:-60} \
    ${PYTHON:-python} -m subunit.run discover -t ./ ./ --list
    db type could not be determined
    error: testr failed (3)

This happens because the apparently the times.dbm file generated
by py27 is not compatible with py34. The converse is not true though -
if you run py34 first, py27 will work.

Both these bugs have been filed against it, but I see no resolution
https://bugs.launchpad.net/testrepository/+bug/1212909
https://bugs.launchpad.net/testrepository/+bug/1229445

The work-around is to delete the file, which is what I propose
to do before running every tox test. I know this isn't optimal, but
neither is hitting this bug repeatedly. :)

    Remove times.dbm file for each tox run

    If you run the py27 tox tests then attempt to run the py34 tests,
    the following error will occur:

        py34 runtests: commands[0] | ostestr
        --blacklist_file=blacklist-py3.txt
        db type could not be determined
        running=${PYTHON:-python} -m subunit.run discover
        ./trove/tests/unittests --list
        The test run didn't actually run any tests

    This happens because the apparently the times.dbm file generated
    by py27 is not compatible with py34. The converse is not true though -

    This was originally noticed in python-troveclient, however it
    also manifests in the Trove project.

    coverage.xml was also added to the .gitignore file as it
    was appearing in the git list of modified files.

[Luigi Toscano (ltoscano)]

Can this be really fixed instead of workarounding it?
Also, according the comment in https://review.openstack.org/#/c/467828/, switching to stestr (which we are doing in this Queens cycle) will solve it.
I'm thus marking this "invalid" for Sahara.

This is a workaround, see the comment in https://review.openstack.org/#/c/467828/
