feat(rnd): Add IPC support on autogpt_server (#7212)

### Background

This PR adds support on IPC on autogpt_server.
To make this happen, there are a couple of refactoring efforts being made (will be described in the `Changes` section).
Currently, there are three independent processes:

```
AgentServer ----> ExecutionManager
    | 
     --> ExecutionScheduler
```


### Changes 🏗️

* Added Pyro5 for IPC support.
* Introduced `AppService`: a class to construct an independent process that can expose a method to other running processes (this is analogous to a microservice).
* Introduced `AppProcess`: used by `AppService` a class for creating a child process that can be executed in the background.
* Adapting existing codebase to user `AppService`.
