Implement shareholder token model

[gregdhill]

There are many stakeholders in the system which are incentivized in different ways:

• Collators collect rewards from preparing blocks
• Vaults (both operators and delegators) provide capital to bridge BTC and receive fees / block rewards
• Lenders provide capital and receive fees / incentives
• AMM LPs provide capital and receive fees / incentives
• vKINT / vINTR holders receive block rewards
• External providers (such as developers) can propose receiving funds from treasury

Tokens need to be staked to govern the system (vKINT / vINTR) and those holders should ensure that all suppliers are paid fairly according to the services that they provide. We have many revenue sources (such as bridge fees, XCM fees and lending / AMM fees) which should be pooled into a single community fund and distributed across all our stakeholder groups on a rolling basis.
