Subject: Adding support for LSP `window/showMessage` method (#2652)

* Added base handling for window/showMessage
* Ignoring severity log
* Code formatting
* Added user configurable severity
* Preferring ale#util#ShowMessage over echo'ing directly
* Using format similar to ale_echo_msg_format for consistency
* Updating docs
* Added LSP log config string; improved tests
* Use warning as fallback for incorrect user config
