Kill CRV gauge emissions for decprecated crvUSD stableswap pools

Proposals
#1

Summary:

Kill gauges to several crvUSD stableswap pools that have been deprecated due to faulty oracle in the pool implementations. Affected pools have been redeployed and have passed gauge votes, except for crvUSD/USDM.

Abstract:

Pools needing to kill gauge:
