Allow Logging Interceptor to be toggled by Message Logging Enabled Fl…

…ag (#940)

* Update audit.logging.messageLoggingEnabled to be able to enable/disable logging interceptor

Previously the flag only toggled AuditLogger codebase

* Remove disable at AuditLogger for messageLoggingEnabled as it already disabled at the GrpcMessageInterceptor

* Remove legacy logging config file.
