refactor: remove custom access logger

It is fine when application is able to log request, however, normally it
produces a lot noise, which has been handled by adding special logger.
However, nowadays it requires a lot endpoints to be filtered and doesn't
provide any choice.

Instead of it lets disable access logger by default and let users decide
do they need or not to see access log messages
