* use tests to check old configuration values are caught
* add tests for specific key errors
* resolve merge conflicts

* [FEATURE] File Secret Loading

* implement secret testing
* refactor the secrets validator
* make check os agnostic

* rename Validate to ValidateConfiguration
* add k8s example
* add deprecation notice in docs and warning
* style changes
* [MISC] Ignore errcheck recommendations for legacy code
Some of this is likely intended to stay how it is, some could use refactoring, for now we will mark is and ignore it from the linter to be potentially addressed in the future.
* [MISC] Ensure files are gofmt-ed
* 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
