This proposal, if approved, will:

- Authorize runtime upgrade to release `v22` runtime version `hydradx/201`
    - **feat: referrals** by @enthusiastmartin in #708
    - full release notes can be found [here](https://github.com/galacticcouncil/HydraDX-node/releases/tag/v22.0.0)
    
- Create the following on-chain remark: `Withdraw all WBTC (MRL) (19) and iBTC (11) Omnipool positions, create stablepool containing WBTC MRL and iBTC, add the asset shares into Omnipool and fast-track the respective addToken referendum`

-----
Referrals pallet will allow the creation of referral codes - which, once bound to trader accounts, will generate trading fees for:
- the referrer account
- the trader
- HDX stakers

Recently, asset (LP) dynamic fees were "unleashed" and now 50% of all asset (LP) fees will go to the referral pot to be split between the above parties, dependent on the "tier" of the referral codes in use - more information coming in our docs soon.

This initiative is intended to drive considerably higher volumes to HydraDX.
