Use source balancing to transition to centos7

Browse Source 
We currently see some odd behavior with shallow clones using the
leastconn balance method. Theory is that having a mix of centos6 and
centos7 git backends introduces this as a client may end up talking to
different git versions on the backends. Using a specific backend never
has an issue but using the haproxy load balancer does have problems
occasionally.

Work around this by forcing each client to use a single backend via the
source haproxy balance method. Then when the entire cluster of backends
is centos7 based we can switch back to leastconn balancing.
