2022-01-13 bitAssets parameter adjustments

Reason:
The Mekong update (BitShares 6.x) is done, migrating to a new model.

bitCNY parameter update:
* ICR reduced from 185% to 175%
* BSRM adjusted from "global settlement" to "individual settlement to fund"
* Remove limitation on maximum supply
* Enable force settlements

bitUSD parameter update:
* ICR reduced from 300% to 135%
* MCR reduced from 150% to 125%
* Disable collateral bidding
* Remove limitation on maximum supply
* Minimum feeds adjusted to 2 so that price feeds will show on GUI normally
* Update price feed producers list
* no update on BSRM because bitUSD is already globally settled. Will update after revived. The revive price is around 0.06 USD/BTS

bitEUR and bitRUBLE:
* BSRM adjusted from "global settlement" to "individual settlement to order"
* Maximum force settlement volume per hour adjusted from 0.01% to 0.5%
