Fix a problem where ETR would not respect quotation marks

Description of the Change

Make sure we get the input parameters as an array instead of "mushing" them into a string. This makes sure that all parameters are sent to the $COMMAND as they were passed to the executor.sh script, making the script more robust.
When debugging this problem I ran a tool called shellcheck which gave some comments on the script that I fixed as well.

I noticed that a few tests threw a ton of errors in the logs (without failing the tests) that I fixed and I also had to fix a few things that failed when running tox.

Alternate Designs

None!

Possible Drawbacks

This is a change in behavior. It should be more robust, but we don't know if there are any users that depend on the flaky behavior that we have now. We need to test this rigorously and it should be a major release tag on ETOS.
