Added new global_replica_status.sh script v1.0.1 to query status
of replicas on all replica hosts configured with the SDP.
Renamed sdp_sync.cfg to more generic sdp_hosts.cfg, as it is
now used by both sdp_sync.sh and global_replica_status.sh.
* Changed '-h <hosts>' flag to '-H <hosts> to avoid conflict
with the '-h' (help) flag.
* Fixed bug with default P4U_LOG setting.
* Refined command line processing and environment handling.
* Updated with latest changes from template.sh, so it now
picks accepts the '-V' (show version info) flag.
