* Unbreak oauth2-proxy for keycloak provider after 2c668a
With 2c668a, oauth2-proxy fails a request if the token validation fails.
Token validation always fails with the keycloak provider, due to the
valudation request passing the token via the URL, and keycloak not
parsing the url for tokens.
This is fixed by forcing the validation request to pass the token via a
header.
This code taken from the DigitalOcean provider, which presumably forcing
the token to be passed via header for the same reason.
Test plan: I was unable to build a docker image to test the fix, but I
believe it is relatively simple, and it passes the "looks good to me"
test plan.

* Change error type for redirect parsing errors
This changes the error type returned when the proxy fails to parse the
redirect target to be a 400 error instead of a 500 error.
As far as I can tell, the only way that this can fail is a failure to
parse the properties of the request to identity the redirect target.
This indicates that the user has sent a malformed request, and so should
result in a 400 rather than a 500.
I've added a test to exercise this, based on a real work example.

* 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`.
