stats/vty: Add stats configuration
This commit provides stats configuration similar to the log configuration. The following vty commands are added to the config node: stats reporter statsd Create/Modify a statsd reporter no stats reporter statsd Remove a statsd reporter To actually configure a reporter, the config-stats node is entered when the "stats reporter" command has succeeded. The following new vty commands are available there: local-ip ADDR Set the IP address to which we bind locally no local-ip Do not bind to a certain IP address remote-ip ADDR Set the remote IP address to which we connect remote-port <1-65535> Set the remote port to which we connect prefix PREFIX Set the item/counter name prefix no prefix Do not use a prefix enable Enable the reporter disable Disable the reporter Sponsored-by: On-Waves ehf
