Bot monitoring

### Feature Suggestion

####V1
Use the EMQX protocol, to fetch:
- bot state
- PnL
- Open orders
- Inventory

And expose through the API.

#### V2
Instead of REST, use WebSockets to get a live stream of open and filled orders (which is its own endpoint)

### Impact

User is able to monitor bot (live) performance.
