* refactor: logging config key to log
This refactors the recent pre-release change adding log options to their own configuration section in favor of a log section (from logging).
* docs: add step to getting started to get the latest tagged commit
This is so we avoid issues with changes on master having differences that don't work on the latest docker tag.
* test: adjust tests
* docs: adjust doc strings
This is so levels like warn and error can be used to exclude info or warn messages. Additionally there is a reasonable refactoring of logging moving the log config options to the logging key because there are a significant number of log options now. This also decouples the expvars and pprof handlers from the log level, and they are now configured by server.enable_expvars and server.enable_pprof at any logging level.
Updated all links to use https://www.authelia.com/docs/.
Removed all comment sections from documented configuration on the documentation site and replaced them with their own sections.
Made all documentation inside config.template.yml double hashes, and made all commented configuration sections single quoted.
Added .yamllint.yaml to express our desired YAML styles.
Added a style guide.
Refactored many documentation areas to be 120 char widths where possible. It's by no means exhaustive but is a large start.
Added a statelessness guide for the pending Kubernetes chart introduction.
Added labels to configuration documentation and made many areas uniform.
