If the connection to the primary is lost, roll back to the previously
known state.
TRUNCATE is of course not MVCC-friendly, but that shouldn't matter here
as only one process should ever be looking at this table.

Although the witness server will resync the repl_nodes table following
a failover, other operations (e.g. removing or cloning a standby)
were previously not reflected in the witness server's copy of this
table.
As a short-term workaround, automatically resync the table at regular
intervals (defined by the configuration file parameter
"witness_repl_nodes_sync_interval_secs", default 30 seconds).

This fixes a bug introduced into the previous commit, where the
witness node was registered last to prevent a spurious node record
being created even if witness server creation failed.
Ensure witness is only registered after all steps for creation
have been successfully completed.
Also write an event record if connection could not be made to
the witness server after initial creation.
This addresses GitHub issue #146.
99.9% of the time they'll be the same as the primary connection, but
it's more consistent to use the provided local conninfo string
(from which the port is already extracted).
Optionally prompt for superuser and repmgr user when creating a witness.
This ensures a password can be provided if the primary's pg_hba.conf
mandates it.
This deprecates '--initdb-no-pwprompt'; and changes the default behaviour of
"repmgr create witness", which previously required a superuser password
unless '--initdb-no-pwprompt' was supplied.
This behaviour is more consistent with other PostgreSQL utilities such
as createuser.
Partial fix for GitHub issue #145.
