STORM-2500: remove call to waitUntilReady

[ZacharyThomas]

In 1.1.x PacemakerClient was refactored so waitUntilReady was private, and called by the send method. But this clojure reference remained, causing pacemaker to fail to initialize. AFAIK this reference can simply be removed, as waitForReady is called on send. However, I'm not very familiar with the code base. I applied this patch to our own cluster with success.

This fixes what #2142 already fixed, but no activity is seen on #2142 I'll just merge this.
Travis CI fails on all JDK7 builds, hence not related to this.

@ZacharyThomas
Thanks for the patch. I merged this but can't update assignee on issue (https://issues.apache.org/jira/browse/STORM-2500).

Could you let me know your Apache JIRA ID? Thanks in advance!

@HeartSaVioR It was fun. Encountered this while trying to debug the exclamation topology dying on a new cluster (see: https://mail-archives.apache.org/mod_mbox/storm-user/201708.mbox/%3CCA%2BAmaO0oP5imSgs7nXboM_VQva0PzoQNGGURG%2BfR3rySystm1g%40mail.gmail.com%3E)

Which, if you have any suggestions for, that'd be great.
