c19e7f1025 "cluster show": output any connection error messagesin list of warnings 
This ensures any connection errors are displayed by default in a
comprehensible, easily reportable way, and saves having to request/filter
DEBUG output.

Implements GitHub #369.

f96cc3b906 "cluster show": improve handling of database errors 
In particular, if running "repmgr cluster show" against a database
without the repmgr metadata, showing the error (rather than just
"no records found" etc.) will provide some clues about the problem.

c0a53471e1 "standby switchover": improve log messages and add new exit code 
Previously, if an issue was encountered with the old primary, but user
provided -F/--force to have repmgr promote the standby anyway, repmgr
would exit with the log message "STANDBY SWITCHOVER is complete"
and exit code 0 (SUCCESS).

To better report this partial completion, repmgr will now emit the message
"STANDBY SWITCHOVER has completed with issues" (and a HINT to check preceding
log messages) and new exit code 22 (ERR_SWITCHOVER_INCOMPLETE).

2eec8b5d79 Have do_standby_follow_internal() not abort on error 
Pass the error code back to the caller instead, mainly so
"repmgr node rejoin" can better report errors.

c11e92cf2a repmgr: improve switchover handling when "pg_ctl" used 
If logging output not explicitly rediretced with "-l" in the pg_ctl
options, repmgr would hang waiting for pg_ctl output.

Note that we recommend using the OS-level service commands where
available.

ae7963dc64 repmgr: automatically create slot name if missing 
It's possible that a node was registered with "use_replication_slots=false"
but that was later changed to "use_replication_slots=true". If the node
was not subsequently re-registered, the node record will contain an empty
slot name, which will cause any slot creation operation during
"standby follow" or "node rejoin" to fail.

To prevent this happening, check for an empty slot name and automatically
set before proceeding.

Addresses GitHub #343.

the call in repmgrd-bdr.c was only accidentally working; explicitly
test for a false return value.

aee12dc2c7 "repmgr bdr register": create missing connection replication set if needed
