[TACHYON-196] [TACHYON-185] added test to verify that the http server is working

Relates to https://tachyon.atlassian.net/browse/TACHYON-196 and #492 

The root cause was that when max threads is larger than min threads, jetty logs a error and does nothing.  Made min/max the same size and added tests to prove that this is working moving forward
