Add cmirror - the Cluster Mirror user space component to RHEL 5.3

<Feature Updates Comments> LVM-based Cluster mirroring This addition gives users the ability to create LVM mirrors in a cluster environment (i.e. while using CLVM). It provides for simultaneous access from multiple cluster machines, like when using a cluster-aware file system. The solution is compatible with existing single-machine mirrors. When switching a mirrored volume from single-machine to cluster-aware, no resynchronization is necessary. <Feature Updates Comments/>

Did we want to mention that only 2 leg mirrors are supported for 5.3?

yes. If you switch from a cluster to one machine and change the volume group attribute from clustered to not-clustered, it will still be compatible.
release notes updated to reflect comment 13 and 14
