[GIP-132]: Additional reserve price feeds

Author: van0k.eth

Summary

This proposal aims to add reserve price feeds for DEX-tradable assets that didn't previously have price feeds, and LP assets that have alternative price feed options readily available.

Motivation

Currently a lot of assets in the system do not have reserve price feeds. This generally prevents withdrawals from accounts where those assets are used as collateral, but, most importantly, this prevents partial liquidations, since they currently rely on withdrawals being available.

Specification

The following assets will receive Redstone pull feeds as reserve feeds:

1. LDO - Redstone price feed - https://app.redstone.finance/#/app/token/LDO
2. APE - Redstone price feed - https://app.redstone.finance/#/app/token/APE
3. crvUSD - Redstone price feed - https://app.redstone.finance/#/app/token/crvUSD
4. GHO - Redstone price feed - https://app.redstone.finance/#/app/token/GHO
5. 3crv - Redstone price feed - https://app.redstone.finance/#/app/token/3Crv
6. crvFRAX - Redstone price feed - https://app.redstone.finance/#/app/token/crvFRAX
7. sDAI - Redstone price feed - https://app.redstone.finance/#/app/token/sDAI
8. sUSDe - Chainlink price feed - https://etherscan.io/address/0xb99D174ED06c83588Af997c8859F93E83dD4733f
9. USDe - Redstone price feed - https://app.redstone.finance/#/app/token/USDe

Additionally, USDe main price feed will be changed to Chainlink feed from current Redstone push feed.
