Move REST API test scripts into a common directory

Moved and renamed the starting and stopping scripts from the REST API
tests to a common directory. This way the MaxCtrl tests can use the same
scripts to start and stop MaxScale.

Also moved the test configuration file into the `test/` directory and
changed some of the default directory locations.
