Add Open Text Proposals

[ethanfrey]

The requirement is to have a mechanism to be able to create an Open Text proposal so that a decision is recorded on-chain. Note it is not a binding agreement.

Issue confio/tgrade-app#274 for the UI design. UI coding tickets will follow once the design is in place.

We need a new proposal type Text{} that has no extra fields besides the existing title and description.

When passed, it saves the title and description in the storage. It takes no other actions.

These stored proposals can be queried or listed.

Which contracts are affected?

• oversight community
• arbiter pool
• validator voting
• community pool

This is not included in trusted-circle

To avoid copy paste, a small package for this logic would be nice...

Defining execute_text to handle when passed, and query_text_proposal / list_text_proposals to view the previously based ones

I tried implementing something generic in voting-contract with type magic 🪄 - basically a wrapper around any custom Proposal type that enriches it with a Text variant. I could get it to serialize transparently with serde_json, but not with serde_json_wasm.

It's probably solvable with a shared lib by

• doing type wizardry, but implementing a custom serializer/deserializer
• macros
• seeing if Library panics when deserializing certain types due to unreachable!() statements rust-embedded-community/serde-json-core#48 can be fixed, maybe? looks related
• the ng stuff?

Either way, it's probably too much. I'm going to do it the easy way for now. Feel free to poke me and take this over if you have cool ideas about how to solve it better.

Work done in #27:

• The logic for text proposals was added to the voting-contract lib.
• Contracts tgrade-community-pool and tgrade-validator-voting now implement text proposals.

We can deal with the arbiter pool and OC after a release of poe-contracts.
