Multi Asset (Sub-)Treasuries

[joepetrowski]

The Vision

High level described in https://forum.polkadot.network/t/collective-based-multi-asset-treasuries/2899

A Treasury can generally be thought of as (1) logic for spending assets, and (2) the assets themselves. The network may have multiple treasuries (e.g. a primary Treasury where inflation goes, but also collective-based treasuries).

• Users can make Treasury spend proposals in any asset.
• The Treasury is able to collect its funds on Asset Hub (e.g. have the Relay Chain DOT sent to AH when needed).
• The logic for a given Treasury "lives" in one place, probably the governance location. As in, for example, the Fellowship's Treasury would be on the Collectives parachain. However, the assets a Treasury holds can exist in many places (many other chains).
• A Treasury can schedule future spends that can be voided by another referendum. This should generally replace bounties.

The Plan

• Primary implementation: Treasury spends various asset kinds polkadot-sdk#1333
• Get subscriptions for Asset Rate Allow Asset Conversion Subscriptions polkadot-sdk#101
• Add instances of the Treasury pallet with collectives (Fellowship, Ambassador Program, &c.).
• Configure Asset Hub with a computable AccountId for each Treasury and means of recognizing spend origins.
• UI &c. support.
