Allow instance of general agent to pick up tasks from task incentivization system

[gabrielfior]

@kongzii please adjust the description if needed:

--
-> General agent should have a function that allows it to find job tasks (defined as Prediction Markets)
-> It should be able to decide am I able to complete this task? and is fulfilling this task profitable?
-> It should be able to post its answer somewhere so that it can claim the bounty later

@gabrielfior all of that is already implemented in https://github.com/gnosis/prediction-market-agent/blob/ec52359c9d38fcde80f51c4d5bb69d1e77734a7b/prediction_market_agent/agents/microchain_agent/jobs_functions.py#L1
