text: Title: Feature: add K8S probes checker API
  Body: We should provides users with an ability to check application health in a some way. It can be reached by using multiple mechanism, so we can create a base `Checker` Protocol and use it the following way
  
  ```python
  app = FastStream(broker)
  app.add_checker(
       SocketChecker("/sock"),
       # HTTPChecker(port=8000),
       # ...
  )
  ```
  
  And check all of them by the same command
  
  ```shell
  faststream probe main:app
  ```
  
  So, we can create multiple checkers for various cases and user can implement any checker by itself in the same time
  
  
  * [x] add `broker.ping()` unified method
  * [ ] add `BaseCheker` using `broker.ping()`
  * [ ] implement `HTTPChecker` (inheritor of `BaseCheker`)
  * [ ] add CLI command to use any checker
