Zamil Majdy bb92226f5d feat(backend): Remove RPC service from Agent Executor (#9804) ...

Currently the execution task is not properly distributed between
executors because we need to send the execution request to the execution
server.

The execution manager now accepts the execution request from the message
queue. Thus, we can remove the synchronous RPC system from this service,
let the system focus on executing the agent, and not spare any process
for the HTTP API interface.

This will also reduce the risk of the execution service being too busy
and not able to accept any add execution requests.

### Changes 🏗️

* Remove the RPC system in Agent Executor
* Allow the cancellation of the execution that is still waiting in the
queue (by avoiding it from being executed).
* Make a unified helper for adding an execution request to the system
and move other execution-related helper functions into
`executor/utils.py`.
* Remove non-db connections (redis / rabbitmq) in Database Manager and
let the client manage this by themselves.
