Implement scalability refactor for miner

[juanmanso]

Description

After masa-finance/bt-refactor-spike#1, we are now able to put this refactor into action on the masa-bittensor repo.

TL;DR for planning:

• use self.axon.attach() for miner instead of what we have now
• define a way to generate synapses for each task
• follow the folder structure suggested

Use as reference the draft PR which spikes the implementation

Acceptance criteria

• Regression testing proof showing that functionalities persist
• Goals of masa-finance/masa-bittensor#71 are met

I think this is ready for development

EDIT: I think that triage here means that it might not be well defined. What I meant with the previous text is that I think this is defined enough so we can remove the triage label and as a team select it for ready either above or below the waterline
