ARI: Rotate log channels.

An http request can be sent to rotate a specified log channel.
If the channel does not exist, an error response will be
returned.

The command "curl -v -u user:pass -X PUT 'http://localhost:8088
/ari/asterisk/logging/logChannelName/rotate'" can be run in the
terminal to access this new functionality.

* Added the ability to rotate log files through ARI
