repmgr: have "cluster show" exit with a non-zero value if issues detected

Browse Source 
If any issues are detected (e.g. node not reachable, unexpected node status
etc.), "repmgr cluster show" returns exit code 25 ("ERR_NODE_STATUS").

Note that exit code 25 was introduced recently as "ERR_CLUSTER_CHECK",
however it makes sense to use this to indicate issues detected by any
command which can detect node issues.

Addresses GitHub #456.
