floto logging

This PR proposes the introduction of log handlers for floto.
As floto is a library the handlers are not created inside floto. Instead it's done via logging configuration.

Changes proposed in this pull request:

• template yaml files for the logger set up: See examples/hello_world.py / logging/*.yml
• Introduction of floto.utils.logging_filter classes which add context information and the identity to the log record: Used in floto.ActivityWorker

Todos

• Add context information to decider loggers
• Add environment information (staging/production) to Logger
• Move all logger to class level instead of module level
• Add use case driven loggers, e.g. CloudWatch / Monitor logger

This is considered WIP, please have a look and comment on the "pattern". When the pattern is right, I'll add the missing parts.
