Description

As discussed in [0] in deployments involving a CRX cluster in active/passive setup, it would be beneficial to allow the Sling leader to match the CRX master at all time, thus avoiding to write on the CRX slave.

This issue is about enabling this as an optional support. This is only relevant for setups on CRX and should not impact other clustering technologies.
