* feat(logging): allow time replacement in log file name
This allows replacing `%d` with a date time format in the log `file_name` option.
Closes#3210.
This change adjusts several global options moving them into the server block. It additionally notes other breaking changes in the configuration.
BREAKING CHANGE: Several configuration options have been changed and moved into other sections. Migration instructions are documented here: https://authelia.com/docs/configuration/migration.html#4.30.0
* 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.
