Add support for Automated payment of OC/AP members

[pinosu]

Implement blockchain part related to tc-payments contract.

TODOs:

1. Store and instantiate this contract in the chain. That means, a contract "upgrade" proposal for tc-payments.
2. Modify tgrade so that it calls this contract's end blocker. That means, a tgrade chain upgrade proposal.
3. Modify valset distribution so that it sends the engagement funds to this contract instead to the engagement contract. That means, a valset contract upgrade proposal, as the distribution list is currently not part of the update config mechanism (tgrade-valset: Modify distribution list to send funds to tc-payments poe-contracts#182).

Release 0.14 of tgrade-contracts is required beforehand.

Modify tgrade so that it calls this contract's end blocker. That means, a tgrade chain upgrade proposal.

No need to upgrade the chain. When when.a contract is promoted to "privileged" (via gov proposal), a callback to the contract is sent to let it register for chain permissions (end blocker in this case).

Release 0.14 of tgrade-contracts

The repo was tagged 3 days ago. ( https://github.com/confio/poe-contracts/releases/tag/v0.14.0) do you mean v0.15 ?

Nice! Didn't knew that.

tc_payments is part of tgrade-contracts, not poe-contracts. This requires a new release of tgrade-contracts.

In fact it will be good to release a new poe-contracts as well, just to update cw and cw-plus dependencies to latest.

The only problem is that that gov proposal (PromoteToPrivilegedContract) is currently unimplemented in the validator voting contract (confio/poe-contracts#158).

Will implement that, and we would finally have a route for storing, instantiating, promoting and wiring the payments contract.

[daniellarita]

Ok thanks. So it looks like there isn't anything that needs to be done on the blockchain side.

@maurolacy have you had a chance to implement PromoteToPrivilegedContract?

[maurolacy]

Yes, this is already done (see confio/poe-contracts#188).

In fact the validator-voting contract with these changes is already deployed and migrated. See proposal number 8 in tgrade mainnet.
