Run integration tests from one file

[sajith]

It would be useful to be able to run integration tests using tox like:

$ tox -e integration -- integration/test_web.py

such that tox will run just the tests in integration/test_web.py. This will be a one-line change in tox.ini, from:

py.test --coverage -v integration/

to

py.test --coverage -v {posargs:integration/}

Pass posargs to py.test when running integration tests

Running "tox -e integration" takes a while. It would be helpful to
run tests from just one file. With this change, we can do that, like
so:

$ tox -e integration -- integration/test_web.py

Or even just one test, like so:

$ tox -e integration -- integration/test_web.py::test_index

With this investigating failing integration tests will be a little
easier, hopefully.
