Release 1.9.0: Simplify Vault Reward Supply Setting

### Summary

This proposal activates KINT staking rewards as of block 599997 - that is, around 15 March 12:00 UTC (depending on block times). *[Update: due to slower block times, rewards will likely activate around March 16th EOD UTC]*

### Proposal

The Interlay team has informed the community in a discussion post that the staking rewards can be activated. 

The next step is hence to activate staking rewards via an on-chain governance proposal.

### Requesting TC Fast-track

Since everything is ready and the community has been waiting for staking to be activated, a fast-track by the Technical Committee is requested. This way, staking rewards can go live on March 15. Without TC, this would be delayed by another 2 weeks (up to 7 days before the proposal becomes a referendum, and another week of voting and enactment).

Release 1.8.1: Upgrade Kintsugi to polkadot 0.9.17 and fix a difficulty check bug in the btc-relay

The stable parachain confirmations had been set to 600 parachain blocks. However, this was using 6-second block times that are standard in standalone mode. This proposal corrects the parachain confirmations to 300 blocks accounting for 12-second block times in the parachain mode.

The arguments are obtained as follows:
- storage key obtained by going to chain state -> btcRelay -> stableParachainConfirmations. It shows the encoded storage key.
- The value should be 300 (because 300 * 12 = 3600), which in hex is 0x12c. Encoded in 32 bit little endian this is 0x2c010000

Account for 12 second block times in stable parachain confirmations

This is part 2/2 to open the bi-directional channel with Karura. See [referendum #7](https://kintsugi.subsquare.io/democracy/referendum/7) for more details.

Open XCM channel with Karura - Part 2/2 (HRMP ACCEPT)

Before releasing kBTC, we remove all currently unused oracle accounts. Oracles should be added later via a governance process and then dedicated accounts should be added instead, or, better, dedicated pallets should be added.

Remove outdated oracle account

# Karura XCM

This referendum opens the XCM channel to Karura. This will allow Kintsugi assets to be transferred to Karura and used there.

This is the first part of two referenda to open bi-directional communication with Karura. The second referendum will accept the open channel to Kintsugi.

Note: Karura needs to pass a referendum as well to accept this open channel.

Note: The proposal was fast-tracked by the technical committee.

# Force XCM

The second part of this proposal enforces all XCM to use V2.

This proposal implements a restriction of voting power for two years for team and investors to ensure that Kintsugi decisions are fully decentralized.

# Background

Since both vested and unvested tokens can participate in voting, the Interlay team and investors introduce additional restrictions on their own voting power during the first 2 years after network launch. Specifically: while the community can use 100% of their vested and unvested KINT to vote, team and investors can only use a portion of their KINT (which is subject to lockup and vesting) to participate in governance - increasing linearly over 2 years.

# Voting Power Distribution

This is part 2/2 to open the bi-directional channel with Mooonriver. See [referendum #4](https://kintsugi.subsquare.io/democracy/referendum/4) for more details.

This referendum opens the XCM channel to Moonriver. This will allow Kintsugi assets to be transferred to Moonriver and used there.

This is the first part of two referenda to open bi-directional communication with Moonriver. The second referendum will accept the open channel to Kintsugi.

Note: Moonriver needs to pass a referendum as well to accept this open channel.

Release 1.7.3: Upgrade Kintsugi to polkadot 0.9.16 and integrate XCM modules for parachain to parachain communication

This referendum has not been executed due to a misconfiguration in the fast-track. Fast-track delay was set to 7,200 blocks. Since this change was needed ahead of time, a new referendum was brought forward instead.
