adding abiltiy to bind driver with dpdk-devbind.py that resides in th…

[PatrickKutch]

I created a new way of binding the driver. There is now a bind_driver_with_dpdk() that uses the dpdk-devbind.py tool that is designed for doing this.

Also created a new execute function called executeWithSearch() that can search stdout for a specified error string - because you cannot get an errorcode from an application run in a container

I've not changed any of the other code (except test_utils::test_bind_driver) to make user of the new bind_driver_with_dpdk(). I wanted to get you guys to look at what I did before we change bind_driver() calls to bind_driver_with_dpdk()

I fixed some of the lintr complaints, but many of these errors are not in my new sections, not sure why this is failing.

@PatrickKutch It is possible that we updated linter settings after the initial code was committed. Would you mind running black formatter against the file?
"'sriov.common.utils.bind_driver' imported but unused" is introduced by your change. Please remove if not used.

Updated.

I'm a little confused why the lint for me fails on things I didn't touch.

@PatrickKutch Let's look at exec.py linter failures. Flake8 reported violations at lines 299. 300, 311. Looking at your diff, these lines are part of the new executeWithSearch. Likewise, utils.py lines 58,76,79 were brought by bind_driver_with_dpdk in your diff. Let me know if I miss anything. I can show you in real time how to make flake8 sriov --count --select=E,C,F,W --ignore W503 --max-complexity=15 --max-line-length=88 --show-source --statistics pass on your fork.
