Optimistic Project Funding

[ndkazu]

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.

Integration

Review Notes

Terminology

The constants available in the runtime for the OPF Pallet:

• MaxProjects: Maximum number of Whitelisted projects that can be handled by the 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
• - claim: To claim a spend

Some pretty superficial notes to start my review. Can continue with a more detailed review later tomorrow.

As a general remark, if you have a voting schema that somehow resembles what's already out there on OpenGov, I suggest you consider exploring the pallets that implement Tally and integrate with pallet-referenda.

@pandres95 and @kianenigma , I have a question: Is there a reason for Not using pallet-democracy?
During the PBA, I was told that open-gov not being one pallet, implementation is a "bit" complex (Is there a resource I can check that is describing how it's done?).
Looking into pallet-referenda & pallet-conviction, It felt like way more work to implement something using both of these pallets together, than simply using pallet-democracy. But I will gladly dive into it, if it is ABSOLUTELY necessary, I just want to understand the "why"...
