This enhances the existing time.Duration parser to allow multiple units, and implements a decode hook which can be used by koanf to decode string/integers into time.Durations as applicable.
Allow users to configure the TOTP Algorithm and Digits. This should be used with caution as many TOTP applications do not support it. Some will also fail to notify the user that there is an issue. i.e. if the algorithm in the QR code is sha512, they continue to generate one time passwords with sha1. In addition this drastically refactors TOTP in general to be more user friendly by not forcing them to register a new device if the administrator changes the period (or algorithm).
Fixes#1226.
This is a massive overhaul to the SQL Storage for Authelia. It facilitates a whole heap of utility commands to help manage the database, primary keys, ensures all database requests use a context for cancellations, and paves the way for a few other PR's which improve the database.
Fixes#1337
* 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
