ARI: Deleting log channels

An http request can be sent to delete a log channel
in Asterisk.

The command "curl -v -u user:pass -X DELETE 'http://localhost:8088
/ari/asterisk/logging/mylog'" can be run in the terminal
to access the newly implemented functionally for ARI.

* Able to delete log channels using ARI

ASTERISK-25252
