* Add the allowed_email_domains and the allowed_groups on the auth_request endpoint + support standard wildcard char for validation with sub-domain and email-domain.

* Fix provider data initialisation
* PKCE Support
Adds Code Challenge PKCE support (RFC-7636) and partial
Authorization Server Metadata (RFC-8414) for detecting PKCE support.
- Introduces new option `--force-code-challenge-method` to force a
specific code challenge method (either `S256` or `plain`) for instances
when the server has not implemented RFC-8414 in order to detect
PKCE support on the discovery document.
- In all other cases, if the PKCE support can be determined during discovery
then the `code_challenge_methods_supported` is used and S256 is always
preferred.
- The force command line argument is helpful with some providers like Azure
who supports PKCE but does not list it in their discovery document yet.
- Initial thought was given to just always attempt PKCE since according to spec
additional URL parameters should be dropped by servers which implemented
OAuth 2, however other projects found cases in the wild where this causes 500
errors by buggy implementations.
See: https://github.com/spring-projects/spring-security/pull/7804#issuecomment-578323810
- Due to the fact that the `code_verifier` must be saved between the redirect and
callback, sessions are now created when the redirect takes place with `Authenticated: false`.
The session will be recreated and marked as `Authenticated` on callback.
- Individual provider implementations can choose to include or ignore code_challenge
and code_verifier function parameters passed to them
Note: Technically speaking `plain` is not required to be implemented since
oauth2-proxy will always be able to handle S256 and servers MUST implement
S256 support.
> If the client is capable of using "S256", it MUST use "S256", as "S256"
> is Mandatory To Implement (MTI) on the server. Clients are permitted
> to use "plain" only if they cannot support "S256" for some technical
> reason and know via out-of-band configuration that the server supports
> "plain".
Ref: RFC-7636 Sec 4.2
oauth2-proxy will always use S256 unless the user explicitly forces `plain`.

* Set and verify a nonce with OIDC
* Create a CSRF object to manage nonces & cookies
* Add missing generic cookie unit tests
* Add config flag to control OIDC SkipNonce
* Send hashed nonces in authentication requests
* Encrypt the CSRF cookie
* Add clarity to naming & add more helper methods
* Make CSRF an interface and keep underlying nonces private
* Add ReverseProxy scope to cookie tests
* Align to new 1.16 SameSite cookie default
* Perform SecretBytes conversion on CSRF cookie crypto
* Make state encoding signatures consistent
* Mock time in CSRF struct via Clock
* Improve InsecureSkipNonce docstring
This includes a fix for our samesite cookie parsing. The behaviour
changed in 1.16 so that the default value now leaves it empty, so it's
equivalent to not setting it (as per spec)
Reorganized the structure of the Request Utils due to their widespread use
resulting in circular imports issues (mostly because of middleware & logger).
* Allow multiple cookie domains to be specified
* Use X-Forwarded-Host, if it exists, when selecting cookie domain
* Perform cookie domain sorting in config validation phase
* Extract get domain cookies to a single function
* Update pkg/cookies/cookies.go

Values of 'lax' and 'strict' can improve and mitigate
some categories of cross-site traffic tampering.
Given that the nature of this proxy is often to proxy
private tools, this is useful to take advantage of.
