Test Timeout Failures

Travis has extremely underpowered instances which cause certain tests to timeout. The following is a list of failures we saw in travis including pull request numbers if they have been addressed:

• must reach a decision for lots of slots *** FAILED *** [info] Wal 1 did not contain expected number of events (49 out of 50) (FullSystemITest.scala:234)
• should be able to make progress with SSL turned on FAILED [info] Membership did not reach expected size: expected 3, got List(3, 3, 3) (FullSystemITest.scala:172)
