* Fix pytype error:

File "websocket/_wsdump.py", line 107, in <module>: Overriding method signature mismatch [signature-mismatch]
  Base signature: 'def code.InteractiveConsole.raw_input(self, prompt: str = ...) -> str'.
  Subclass signature: 'def RawInput.raw_input(self, prompt) -> Any'.
  Parameter 'prompt' must have a default value.

* Fix pytype error:

File "websocket/tests/echo-server.py", line 18, in main: Function Serve.__init__ was called with the wrong arguments [wrong-arg-types]
         Expected: (self, ws_handler, host, port: Optional[int] = ..., ...)
  Actually passed: (self, ws_handler, host, port: str)

* Fix undefined variable error found by pytype:

File "compliance/test_fuzzingclient.py", line 57, in <module>: Name 'case' is not defined [name-error]

* fix: pass correct number of params to logging function

* feat: change logging format to string formatting

* Refactor and fix reconnect and ping

- Dispatcher: do not reconnect in loop
- Avoid reconnect in recursion and hit maximum recursion depth
- Close websocket before reconnect to avoid unclosed ssl.SSLSocket warnings
- Start ping thread on socket connect
- Stop ping thread on socket disconnect
- Add reconnect test
- Add callback exception test

* Remove duplicate function

* Also check passed app in testCallbackException

* Test exception in callback method
