Review comment:
Use a new function to log generic log messages, `LOG.logMessage` is used to
log WS messages.

> {quote}{color:#000000}For websocket connections, while generating backend url
> in _org.apache.knox.gateway.websockets.GatewayWebsocketHandler_
> (_getMatchedBackendURL()_ API), Knox appends '_pathservice[1]_' to
> '_backend_' StringBuffer if Service url doesn't end with '/ws'. As a result,
> URI generated had an extra '/' eg:
> {color}{color:#000000}ws://{color}[rafd001-mst-01.cloud.in.guavus.com:11011//_sock/411/anq2kfzp/websocket|http://rafd001-mst-01.cloud.in.guavus.com:11011//_sock/411/anq2kfzp/websocket]{color:#000000}
> and my UI backend which uses SockJS lib was not responding for 2 minutes and
> eventually closing connection.{color}
> {color:#000000}Correct Url which should have been generated is:
> ws://[rafd001-mst-01.cloud.in.guavus.com:11011/_sock/411/anq2kfzp/websocket|http://rafd001-mst-01.cloud.in.guavus.com:11011//_sock/411/anq2kfzp/websocket]{color}
