CI supports for testing dapps on top of a pending proposal

[turadg]

What is the Problem Being Solved?

We have ways to test dapps on top of agoric-3-proposals, which includes only proposals that have executed on the agoric-3 chain.

We have a pipeline of planned proposals in agoric-sdk's a3p-integration directory. It tests integration with agoric-sdk but we don't yet test that other repos (such as dapps) would continue to work if all those pending proposals were executed.

Description of the Design

Build an image such as Agoric/a3p-integration or Agoric/agoric-3-staged that works like agoric-3-proposals but has all the proposals from agoric-sdk/a3p-integration.

Set up CI mechanisms for other repos to run against the chain process run by that image.
