CLONE - Change start priority such that saslauthd starts first

Couchbase is dependent on saslauthd for external auth.  On CentOS 6, the default Couchbase start priority is 50, while saslauthd has a default priority of 65.  This means Couchbase starts before saslauthd, which can cause authentication errors.

I recommend we add the following line to the centos 6 init script:

chkconfig: 2345 70 10
