Subject: [PATCH] Add convenience environment to re-record tests

tox.ini's command specification doesn't expand globs (*) so one cannot
simply do:

    rm {posargs:cratonclient/tests/cassettes/*.yaml}

Instead one must be tricky and use find as we do in this commit. This
also allows folks to simply re-record only the cassettes they wish to
rerecord by doing

    tox -e rerecord -- TestHosts-test_create.yaml

As it will then execute

    find cratonclient/tests/cassettes -name 'TestHosts-test_create' \
        -delete

Or even use globs

    tox -e rerecord -- 'TestHosts*'

As that will translate to

    find cratonclient/tests/cassettes -name 'TestHosts*' -delete

This also ensures that new tests aren't recorded in our py27/py35
environments by setting the appropriate environment variable. Only the
rerecord environment may now record new cassettes.
