"standby clone": improve handling when designated upstream doesn't yet exist
...
This situation can occur in provisioning environments, where a node's
upstream may not exist at the point it's cloned. If replication slots
are in use, we'll need to make sure no attempt is made to create
the replication slot on the designated upstream, as that will end in
tears. We assume the user will be prepared to complete this step manually.

if that's the case, rather than "RUNNING" which is confusing, even
though it's a command for internal use.

Add "repmgr standby follow --upstream-node-id"
...
In an automatic failover situation, after a standby has been promoted
there's a risk the original primary may become available again before
"standby follow" is issued on another standby node, in which case "standby
follow" will reconnect to the original primary.
As the standby's repmgrd will have received a notification from the new
primary, it will know the primary's ID and can therefore explicitly
direct "standby follow" to follow that primary.

Use actual program name rather than "repmgr" when executing remote commands
...
It's possible some distribution packages may assign a different name to the
"repmgr" binary (typically appending a version number), so we shouldn't hard-code
into the command string.
However it's reasonable to assume the "repmgr" binary will have the same name
across a replication cluster so we won't engage in any contortions to account
for possible variations.
