This changes the validation of salts for sha512 to be done by the upstream API rather than locally. This allows the salts used in Linux to be utilized with Authelia provided the hash is a sha512 hash.

* refactor(authentication): use crypto constant time compare
Improve security with usage of the crypto/subtle ConstantTimeCompare() method for hash comparison.
Fixes#1799
* docs: add explicit labels for chat types
* using authelia hash-password if you provide a salt it doesn't encode it as a base64 string
* this causes invalid salts to be stored if a user manually provided one instead of reliance on the automatic generation
* additionally bumped the minimum required salt length to 8 as per reference spec
* additionally removed the maximum salt length as per reference spec (actually 2^32-1 per int32)
* see docs:
* https://tools.ietf.org/html/draft-irtf-cfrg-argon2-10
* https://github.com/P-H-C/phc-winner-argon2
* https://github.com/P-H-C/phc-string-format
* encode all salts
* fix edge case of false positive in CheckPassword
* bump crypt version and fix tests
* only do salt validation in validate salt
* fix tests
* remove panic(err.Error())
* use file mode const
* do hash cleanup on file read instead of check password
* design ConfigAlgoToCryptoAlgo and implement it
* split HashPassword func into functional chunks that could theoretically be reused
* [MISC] Introduce CryptAlgo type.
It helps distinguish between the configuration representation of an algorithm
and the crypt representation (6 and argon2id vs sha512 vs argon2id).
* Add a description to CryptAlgo.
* use const

* [HOTFIX] Prevent Username Enumeration
* thanks to TheHllm for identifying the bug: https://github.com/TheHllm
* temporarily prevents username enumeration with file auth
* proper calculated and very slightly random fix to come
* closely replicate behaviour
* allow error to bubble up
* Synchronize security documentation.

* 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
* [FEATURE] Support Argon2id Passwords
- Updated go module github.com/simia-tech/crypt
- Added Argon2id support for file based authentication backend
- Made it the default method
- Made it so backwards compatibility with SHA512 exists
- Force seeding of the random string generator used for salts to ensure they are all different
- Added command params to the authelia hash-password command
- Automatically remove {CRYPT} from hashes as they are updated
- Automatically change hashes when they are updated to the configured algorithm
- Made the hashing algorithm parameters completely configurable
- Added reasonably comprehensive test suites
- Updated docs
- Updated config template
* Adjust error output
* Fix unit test
* Add unit tests and argon2 version check
* Fix new unit tests
* Update docs, added tests
* Implement configurable values and more comprehensive testing
* Added cmd params to hash_password, updated docs, misc fixes
* More detailed error for cmd, fixed a typo
* Fixed cmd flag error, minor refactoring
* Requested Changes and Minor refactoring
* Increase entropy
* Update docs for entropy changes
* Refactor to reduce nesting and easier code maintenance
* Cleanup Errors (uniformity for the function call)
* Check salt length, fix docs
* Add Base64 string validation for argon2id
* Cleanup and Finalization
- Moved RandomString function from ./internal/authentication/password_hash.go to ./internal/utils/strings.go
- Added SplitStringToArrayOfStrings func that splits strings into an array with a fixed max string len
- Fixed an error in validator that would allow a zero salt length
- Added a test to verify the upstream crypt module supports our defined random salt chars
- Updated docs
- Removed unused "HashingAlgorithm" string type
* Update crypt go mod, support argon2id key length and major refactor
* Config Template Update, Final Tests
* Use schema defaults for hash-password cmd
* Iterations check
* Docs requested changes
* Test Coverage, suggested edits
* Wording edit
* Doc changes
* Default sanity changes
* Default sanity changes - docs
* CI Sanity changes
* Memory in MB
