Subject: start.sh: Use current branch by default
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=97630f0867b8311f81862cc4ee28df677374363c;p=teuthology.git

start.sh: Use current branch by default

Since the main use-case for this work at the moment is self-testing
teuthology, let's make it easy to test the same branch that's being
worked on.
