Post-delta UI improvements

[victorges]

With the Delta upgrade we introduced a few behavior changes, new contracts and interactions with the protocol. We've developed an MVP for the Treasury interaction on the explorer with basic propose, vote, queue & execute workflows. This initial implementation is on #224

There a couple pending features or improvements to make to the interface though. I'll list some of them here that have already been mapped, but there are likely others pending:

• Display treasury contributions transparently on Os history page
• Adjust the "Forecasted Yield" displayed on Orchestrators page based on the current treasury contribution config
• Add support/docs for voting from CLI (depends on livepeer_cli: Implement treasury voting command go-livepeer#2875)
• Display info about which vote was made by yourself/your O on the proposal/voting details, not only "if" it was made
  • This needs some subgraph support indexing the votes
• Allow proposers to cancel their proposal in case they find some mistake (only available before voting starts)
• Adding a more detailed view of the current votes that have been casted on a proposal. Sth like integrating poll-stats directly in the explorer (and for treasury, not governance)
  • This also needs the vote indexing from subgraph mentioned above.
  • In other words, it also means implementing sth like that lateral Votes view from Tally
• Adding support for "cast vote with reason" so voters can explain their support verbally onchain/on the explorer. This would naturally come with support for displaying voters reasons on the more detailed Votes view proposed above
• Maybe: Save proposals details on IPFS instead of embedding them onchain. This should only be necessary if we notice the price for submitting a proposal is too high, as on the MVP we followed the Tally standard of just submitting the text onchain.
• Add current treasury balance on the Treasury page.

Done:

• Add a "badge" to the Treasury tab on top indicating the number of pending/active proposals
  • Implemented on fix: fix active treasury proposals indicator #250
