Revert "Fixing integration tests. Added RethinkDB server fixture. Resurrected fixture logging as print statements for now (will turn into proper logging soon I promise)"

This reverts commit 40e63dcab457693ec3fc5d0d5b24545fdac0d6ab.
Fixing up server integration tests after re-org of testing layout.
Resurrecting server and workspace print statements as logging.
Added configurable kill wait delay and fixture hostname for servers, some things take a while to die (looking at you jenkins). Updated jerkins war location to the place for stock ubuntu (I'm open to suggestions on this).
Working on httpd server fixture. Still to get this going on stock ubuntu (skipped for now),will need to make it smart about the version and system setup.
Added RethinkDB server fixture
