Description

This PR is related to this issue .
Through the introduction of the OPF pallet and the DISTRIBUTION pallet, we are handling the Optimistic Project Funding.
It allows users to nominate projects (whitelisted in OpenGov) with their DOT. This mechanism will be funded with a constant stream of DOT taken directly from inflation and distributed to projects based on the proportion of DOT that has nominated them.

Terminology

The constants available in the runtime for the OPF Pallet:

• VotingPeriod: Period in which people can vote. After the period has ended, the votes are counted (STOP THE COUNT) and then the funds are distributed into Spends.
• ClaimingPeriod: Time for claiming a Spend. After the period has passed, a spend is thrown away and the funds are available again for distribution in the pot.
• VoteValidityPeriod: Period after which all the votes are reset.

Functions

• - register_project: Register by OpenGov, should take AccountId and project Purpose.
• - unregister_project: Unregister by OpenGov

You really only should use conviction-voting, then you don't need to create a proposal etc.

@bkchr & @pandres95, I am trying to understand how to use conviction-voting, and for that I looked into Open-Gov, and all the terminology. My reference point is the democracy pallet as I have experience with it.
My question: by using the Polling trait, doesn't it mean by definition that we have non-bidding votes that do not necessary lead_to/trigger anything happening on-chain? if so, instead of creating a poll with T::Polls::create_ongoing() (which seems to be for benchmarking only, so how do you actually create a poll?) in conviction-voting, shouldn't we use the referenda pallet to create a referendum (submit extrinsic) that will trigger the desired action on-chain. Or am I misunderstanding the difference between a poll creation and a referenda creation?
