Add function create_event_record()
...
For logging an event to the event table without generating an external
event notification.
Rename existing create_event_record*() functions to create_event_notification*()
as this describes their function better.

Rename "logxxx" configuration file parameters to "log_xxx"
...
This is more consistent with other parameters and conforms to
the pattern used by PostgreSQL itself, which uses the prefix "log_"
for logging parameters.
A warning will be emitted if the old version of the parameter name
is detected.

Replace repmgr.conf item "upstream_node_id" with --upstream-node-id
...
This is only relevant when cloning a standby and the node's upstream
can change after failover/switchover etc., so no point keeping the
original value around in the configuration file.

Add configuration option "log_status_interval"
...
Normally (outside of log level DEBUG) repmgrd doesn't generate any
kind of log output, so examining the log file may give the impression
it's not working. Output an informational message at regular intervals
to show it's up and running.

repmgr: fix generation of default "dbname"
...
If not explicitly provided, "dbname" was being set early to the default
"username" value, which was leading to different behaviour to libpq
applications, where "dbname" defaults to "username" at connection
time.
