* add new directive in the global scope `certificates_directory` which is used to bulk load certs and trust them in Authelia
* this is in ADDITION to system certs and are trusted by both LDAP and SMTP
* added a shared TLSConfig struct to be used by both SMTP and LDAP, and anything else in the future that requires tuning the TLS
* remove usage of deprecated LDAP funcs Dial and DialTLS in favor of DialURL which is also easier to use
* use the server name from LDAP URL or SMTP host when validating the certificate unless otherwise defined in the TLS section
* added temporary translations from the old names to the new ones for all deprecated options
* added docs
* updated example configuration
* final deprecations to be done in 4.28.0
* doc updates
* fix misc linting issues
* uniform deprecation notices for ease of final removal
* added additional tests covering previously uncovered areas and the new configuration options
* add non-fatal to certificate loading when system certs could not be loaded
* adjust timeout of Suite ShortTimeouts
* add warnings pusher for the StructValidator
* make the schema suites uninform
* utilize the warnings in the StructValidator
* fix test suite usage for skip_verify
* extract LDAP filter parsing into it's own function to make it possible to test
* test LDAP filter parsing
* update ErrorContainer interface
* add tests to the StructValidator
* add NewTLSConfig test
* move baseDN for users/groups into parsed values
* add tests to cover many of the outstanding areas in LDAP
* add explicit deferred LDAP conn close to UpdatePassword
* add some basic testing to SMTP notifier
* suggestions from code review
* 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
* [FEATURE] Config Validation
* check configuration for invalid keys on startup
* allow users to manually trigger all configuration validation on a file using a cmd
* setup all defaults in config template and run tests against it to prevent accidents
* use tests to check bad configuration values are caught
* use tests to check old configuration values are caught
* add tests for specific key errors
* resolve merge conflicts
* nolint prealloc for test
* 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
