Tighter integration with Flock

[john-light]

Currently the Flock repo states that:

The Aragon Association and representatives of the current Aragon teams will review and approve the relevant applications but the community is invited to participate in the public discussion that will take place in the comments of the relevant pull request. After approval by the Aragon Association, teams must submit a Finance track proposal requesting funding via AGP-1 and ANT holders will approve or reject such proposals.

However AGP-1 does not itself say anything about the Flock process. We should amend AGP-1 to integrate more tightly with Flock, either by incorporating it into the Finance track or creating a separate Flock track.
