Implement timeoutMiddleware and Remove metadata.authorization for src/nodes/agent Domain

[addievo]

Issue is WIP

Specification

1. agentService is a public service, so it should not have authorisation, but in the current implementation, it does. Which is to be altered.
2. agentService currently does not use timeoutMiddleware, which it should.

Additional context

js-rpc has a sister PR which addresses the same issues - MatrixAI/js-rpc#42

Tasks

1. Remove authorisation from AgentRPCRequestParams and AgentRPCResponseResult
2. Implement timeoutMiddleware for agentService

What is AgentService? Does not make sense here.

@CMCDragonkai you asked me to write up this issue, its regarding

// Prevent overwriting the metadata type with `Omit<>`
type AgentRPCRequestParams<T extends Record<string, JSONValue> = ObjectEmpty> =
  {
    metadata?: {
      [Key: string]: JSONValue;
    } & Partial<{
      authorization: string;
      timeout: number;
    }>;
  } & Omit<T, 'metadata'>;

// Prevent overwriting the metadata type with `Omit<>`
type AgentRPCResponseResult<T extends Record<string, JSONValue> = ObjectEmpty> =
  {
    metadata?: {
      [Key: string]: JSONValue;
    } & Partial<{
      authorization: string;
      timeout: number;
    }>;
  } & Omit<T, 'metadata'>;

And the fact that AgentService is a publicly accessible service, consequently it should not have an authorisation field.

Is AgentService actually a class or type? If not don't refer to it in capitalised form.

It is not a class, this issue has something to do with the nodes domain, I don't remember that well, I need to go over this with Brian.

Then rename the pr title. It's confusing.
