[MISC] Update durations to notation format and housekeeping (#824)

* added regulation validator
* made regulations find_time and ban_time values duration notation strings
* added DefaultRegulationConfiguration for the validator
* made session expiration and inactivity values duration notation strings
* TOTP period does not need to be converted because adjustment should be discouraged
* moved TOTP defaults to DefaultTOTPConfiguration and removed the consts
* arranged the root config validator in configuration file order
* adjusted tests for the changes
* moved duration notation docs to root of configuration
* added references to duration notation where applicable
* project wide gofmt and goimports:
* run gofmt
* run goimports -local github.com/authelia/authelia -w on all files
* Make jwt_secret error uniform and add tests
* now at 100% coverage for internal/configuration/validator/configuration.go
