705b52fde4 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.

See: https://github.com/2ndQuadrant/repmgr/issues/323

8e35a415a9 Refactor extraction of value to use for "primary_conninfo" 
Also add improved error detection.

Basically in the worst case we want to enable the user to clone a standby
from Barman even if the upstream node is not running/reachable, as long as
the user explicitly provides a string to use for "primary_conninfo".

8b03859dbe "standby clone": add early sanity check for external configuration files 
This still requires an SSH connection, so we need to check early before
the cloning starts, and also emit useful information for --dry-run.

dc172cae20 When performing a follow operation, start/restart server as appropriate 
Before this we were always forcing a restart, which is technically not
a problem but produces some potentially confusing log entries along the
lines:

  pg_ctl: PID file "/path/to/postmaster.pid" does not exist
  Is server running?
  starting server anyway
