No error raised when slave cannot ssh to the master

[uvdn7]

So far, this is only happening on Mac. If the slave is not in master's authorized_keys list, slave is going to be stuck forever asking for password from the user.

From the slave log: [0m[36m[2015-05-11 11:22:37.960] INFO Bld1-Setup git Command [git fetch --update-head-ok origin refs/clusterrunner/7a3a813a54a37c7215db798e76aec98ed060bf10] had no expected prompts after 10 seconds.

BTW, I created a 'mac' label to track all the Mac specific clusterrunner issues.
