Increase BNC money market target APR to 7% and increase supply cap to $400k of BNC

This proposal will:

1. Increase the target APR (the jumpRate) for the Interlay BNC money market from 4% to 7%.
2. Increase the supply and borrow cap for the Interlay BNC money market from 517k BNC ($125k) to 1.66M BNC ($400k).

Why? The BNC market was originally opened with a supply cap of $350k based on Hydration liquidity of roughly $600k. Since then, the Hydration liquidity of BNC and USDT have increased so much (due to the liquidity marketing initiative) that you can trade a whopping 453k BNC ($108k) before hitting 9% slippage. Based on that, we could safely increase the cap to $600k-$1M. The small $62k BNC loaned on Interlay so far is also 100% borrowed now leading to a borrowing APR of 45%. (it recently was 61-80% borrowed, only spiking the last day) Therefore since our fledgling BNC money market is beginning to grow we should increase the supply/borrow cap on the market to allow it to grow in size. However, some community members are concerned about Interlay money markets being overexposed to Bifrost assets (VDOT). Therefore a compromise is increasing the BNC cap to $400k. I have proposed to the Bifrost community that the Bifrost treasury could deposit BNC protocol owned liquidity into the Interlay money markets to earn additional revenue for the Bifrost treasury; this proposal would create space for that.

The original 4% target APR was based on zero Hydration liquidity marketing and picking an APR below the Bifrost native staking yield. However, with huge demand for Hydration Omnipool farming we should increase the target APR of the Interlay BNC money market in order to grow Interlay revenue since there is now clear market demand. While we are boosting the iBTC target APR to 10% in Interlay ref 116 I propose increasing the BNC APR target to a softer 7% since it was recently less utilized.

This proposal compensates me for 3 hours of research and discussion, testing with Chopsticks and creating the proposal.
