Title: (QA-723) add preserve hosts on failure option to beaker

- still support fast/slow fail modes, in slow mode will continue to
attempt to run tests + test suits
- create preserve_hosts modes:
always = keep 'em around no matter what
onfail = only preserve if there was a failure during testing
never = kill 'em no matter what
- added spec test coverage for these modes
