Add quick start instructions

1

Add tutorial/instructions for how to download and configure ness_rest and run a scan.

Add ability to specify MDM creds with ness_rest

2

It would be handy to be able to specify MDM creds via ness_rest so we don't have to enter the gui when doing MDM scanning.

Refactor our current test_ness6rest.py to use python's unit testing framework and add more tests.

Refactor ness6rest.py to use exceptions instead of sys.exit() and modify ness_rest to catch those exceptions and exit if appropriate.
