5e338473f7 repmgr: before cloning a standby, verify sufficient free walsenders available 
Previously repmgr only checked that 'max_wal_senders' is a positive value.
It will now additionally verify that the requisite number of replication
connections can actually be made before commencing with a cloning operation
using pg_basebackup.

e043d5c9a9 Clarify requirements for passwordless SSH access 
This is already effectively optional; in 3.2 we will ensure it becomes
fully optional (mainly by deprecating --ignore-external-config-files
and replacing it with --copy-external-config-files).

036c59526a repmgr: in switchover mode, prevent checks for local config file if not provided 
In switchover mode, if no remote repmgr config file is provided with `-C`,
repmgr attempts to look for a file with the same path as the local
file (provided with `-f/--config-file`). However if this was not specified,
repmgr would execute `ls` with an empty filepath on the remote host, which
appeared to succeed, causing subsequent remote repmgr command executions
to fail as a blank value was provided for `-f/--config-file`.

Fixes GitHub #229.

3ce231a571 Ensure get_pg_settings() returns false if parameter not found 
Previously, if e.g. a non-superuser connection is used to get a value
like `data_directory`, which is available to superusers only, it
would return true.

135fa2e1b9 Fixing primary_conninfo generation (#232) 
After introducing Barman mode, it is no longer true that STANDBY CLONE
can derive primary_conninfo from the connection to the master. Now we
ask Barman how to connect to a valid cluster node, and then we fetch
the conninfo for the current master from repmgr metadata.
