PKCE implementation (#1784)
* Basic implementation of PKCE

Signed-off-by: Tadeusz Magura-Witkowski <tadeuszmw@gmail.com>

* @mfmarche on 24 Feb: when code_verifier is set, don't check client_secret

In PKCE flow, no client_secret is used, so the check for a valid client_secret
would always fail.

* @deric on 16 Jun: return invalid_grant when wrong code_verifier

* Enforce PKCE flow on /token when PKCE flow was started on /auth
Also dissallow PKCE on /token, when PKCE flow was not started on /auth

* Add "code_challenge_methods_supported" to discovery endpoint

discovery endpoint /dex/.well-known/openid-configuration
now has the following entry:

"code_challenge_methods_supported": [
  "S256",
  "plain"
]

* PKCE: Check clientSecret when available

In authorization_code flow with PKCE, allow empty client_secret on /auth and /token endpoints. But check the client_secret when it is given.

Signed-off-by: Bernd Eckstein <Bernd.Eckstein@faro.com>

* Enable PKCE with public: true

dex configuration public on staticClients now enables the following behavior in PKCE:
- Public: false, PKCE will always check client_secret. This means PKCE in it's natural form is disabled.
- Public: true, PKCE is enabled. It will only check client_secret if the client has sent one. But it allows the code flow if the client didn't sent one.

* Redirect error on unsupported code_challenge_method

- Check for unsupported code_challenge_method after redirect uri is validated, and use newErr() to return the error.
- Add PKCE tests to oauth2_test.go

fd20b213bb storage: fix postgres timezone handling
Dex's Postgres client currently uses the `timestamp` datatype for
storing times. This lops of timezones with no conversion, causing
times to lose locality information.

We could convert all times to UTC before storing them, but this is
a backward incompatible change for upgrades, since the new version
of dex would still be reading times from the database with no
locality.

Because of this intrinsic issue that current Postgres users don't
save any timezone data, we chose to treat any existing installation
as corrupted and change the datatype used for times to `timestamptz`.
This is a breaking change, but it seems hard to offer an
alternative that's both correct and backward compatible.

Additionally, an internal flag has been added to SQL flavors,
`supportsTimezones`. This allows us to handle SQLite3, which doesn't
support timezones, while still storing timezones in other flavors.
Flavors that don't support timezones are explicitly converted to
UTC.
