Instead of -i to install test dependencies, can we have a separate command and/or install them (for all plugins) on startup?

I use bash history a lot and needing to remove the -i the second time i want to excercise the same pulp test is kind of annoying. Leaving it on takes way to much extra time.

Let's install all the test requirements during the compose up. The scripts that run at up time should inspect the DEV_SOURCE_PATH and install the functional and unit test requirments for each plugin listed there.
