Enable UI for proposal funding over multiple pay periods.

Multiple pay period proposal

Description

A dev/dev-team can propose a contract that extends over multiple months with a bimonthly/monthly pay. If the DAO trusts the developer or the team proposing a several month long contract then they need to pass the proposal to pay them just once.

Pros: If the proposal is for project expanding over multiple months, then

1. The DAO does not need to vote on funding the same team for the same project multiple times i.e for every pay period
2. The DAO can still maintain its monthly budget by not paying a huge amount for a long project all at once.

Cons: Once the proposal passes, the funding is approved for all the periods and can't be canceled in the middle.

Hence, the DAO should still approve a huge amount funding only for the known teams/devs that have proved in passed and not for the new teams/devs

User Story

Team X has been involved with the DAO for several months and delivered a great work for their past (couple) proposals and understands the DAOstack architecture pretty well.

The team now has a really cool integration in mind but this would take about 6 months of time for the integration to finish. But if the propose to get funded for 6 months all together, it would be DAOs entire monthly budget, but it makes sense to get funded for all or nothing.

In this situation the team can propose the total amount of funding for the project with 6 periods and each period be month long.

How to

The 4th parameter of the proposeContributionReward is a uint[5] _rewards array and the details for this array is as follows.

rewards[0] - Amount of tokens requested per period
rewards[1] - Amount of ETH requested per period
rewards[2] - Amount of external tokens requested per period
rewards[3] - Period length - if set to zero it allows immediate redeeming after execution.
rewards[4] - Number of periods

Currently, Alchemy UI does not take input for rewards[3] and rewards[4]. The values for these are set to 0 and 1 respectively.

You will have to enable the UI to take input for rewards[3] and rewards[4] in createProposal form.
