Following: #5452

Just enables to offchain worker code that submits the solution back to run a random number of iterations (capped by type MaxIterations). Rest of the changes pertain to fuzzing and testing.

Babe provides "real" randomness, while the one provided by collective flip is based on the last 80? block hashes.
