Subject: [PATCH] Expose CryptoService and RateLimiterRegistry to plugins
 (#6638)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#### What type of PR is this?

/kind feature
/area core
/area plugin
/milestone 2.20.x

#### What this PR does / why we need it:

Currently, we are refactoring login and logout pages to make them extensible. If plugins want to realize a new authentication method, the CryptoService and RateLimiterRegistry may be used to authenticate.

So this PR exposes the two beans to plugins. No side effect will be introduced.

#### Does this PR introduce a user-facing change?

```release-note
【开发相关】允许在插件使用 CryptoService 和 RateLimiterRegistry
```
