Make it clearer that a witness node counts as a "sibling node"
...
It's not attached to the primary per-se, but needs to know what
the current primary is in order to correctly synchronise its
copy of the metadata.
Per GitHub #560 .

standby switchover: ignore nodes which are unreachable and marked as inactive
...
Previously "repmgr standby switchover" would abort if any node was unreachable,
as that means it was unable to check if repmgrd is running.
However if the node has been marked as inactive in the repmgr metadata, it's
reasonable to assume the node is no longer part of the replication cluster
and does not need to be checked.

repmgrd: improve logging of sibling node's upstream info
...
If the sibling node has already been promoted (for whatever
reason, e.g. "repmgr standby promote" was executed manually)
and has exited recovery, the upstream node ID will normally
be reported as "-1", which is correct, but looks confusing in
the logs.
We now only report the upstream node ID if the sibling node
is still in recovery, *or* if it has exited recovery but is
still reporting an extant node ID.

repmgrd: monitor standbys attached to primary
...
This functionality enables repmgrd (when running on the primary) to
monitor connected child nodes. It will log connections and disconnections
and generate events.
Additionally, repmgrd can execute a custom script if the number of connected
child nodes falls below a configurable threshold. This script can be used
e.g. to "fence" the primary following a failover situation where a new primary
has been promoted and all standbys are now child nodes of that primary.
