Add shell script to user#test

This implementation does not yet parse the returned output, but
does succeed in running the RSpec tests and returning the proper
response to the client.
Implement users#test via shell script

Implemented shell script for users#test and parse the results for a
valid HTTP response. The original bug (which arose when sending the
post request to the server via the provided support files) was that
the Test class that was issuing the request had a short timeout.
