* 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`.

You must explicitly configure oauth2-proxy (alpha config only) with which parameters are allowed to pass through, and optionally provide an allow-list of valid values and/or regular expressions for each one. Note that this mechanism subsumes the functionality of the "prompt", "approval_prompt" and "acr_values" legacy configuration options, which must be converted to the equivalent YAML when running in alpha config mode.

`findClaimsFromIDToken` would always have a `nil` access token and not be
able to hit the userinfo endpoint in Bearer case. If access token is nil,
default to legacy `session.Email = claim.Subject` that all JWT bearers used
to have, even if a valid profileURL is present.
This reverts to functionality before #499 where an OIDC
provider could be used with `--skip-jwt-bearer-tokens` and
tokens without an email or profileURL would still be valid.
This logic mirrors `middleware.createSessionStateFromBearerToken`
which used to be the universal logic before #499.
* Add -user-id-claim to support other claims than email
Fix#431 - This is a minimal change to allow the user to configure which claim is
the source of the "user ID".
- Add the option `user-id-claim` (defaults to email)
- OIDC extracts this claim into session.Email (to be renamed later)
- providers: add `CreateSessionStateFromBearerToken` with a default impl taken from
`GetJwtSession` and overridden by oidc to respect `user-id-claim`
Once #466 is merged, I can continue to rename SessionState.Email to .UserID
and add HTTP headers with a corresponding name.

* OIDC Token Refresh works without id_tokens
Addresses https://github.com/pusher/oauth2_proxy/issues/318
Refactoring the OIDC provider so that the refresh process works when there are
no id_tokens present in the response. Added unit tests to the oidc_test.go to prove
the redeem and refresh still work.
The expiry time of the session is now taken from the outh token expiry and not
the id_token (preventing stale access_tokens in sessions).
* Refactoring the to use a KeySetStub in the oidc_test.go. This allows the
elimination of the slightly contrived function passing elements used
previously. (This change is being applied to address the bug #318)
* Changes as per the PR comments and preparing for 5.x release
* Fixup changelog

* Current OIDC implementation asserts that user email check must come
from JWT token claims. OIDC specification also allows for source
of user email to be fetched from userinfo profile endpoint.
http://openid.net/specs/openid-connect-core-1_0.html#UserInfo
* First, attempt to retrieve email from JWT token claims. Then fall back to
requesting email from userinfo endpoint.
* Don't fallback to subject for email
