[BIP-248] Enable COMP/wstETH Gauge [Ethereum]

https://github.com/BalancerMaxis/multisig-ops/pull/137

Summary:

This pool uses the new weighted pool factory which allows us to apply the protocol fee to yield bearing tokens. This gauge would enter as a "core pool" under BIP-19, meaning protocol fees earned by this pool would be used to bribe for votes on it.

Protocol Description:

wstETH is liquid staked ETH. COMP is the governance token for Compound.

Motivation:

Request of master humpy

Specifications:

1. Governance: Find more information about governance on Lido's forum.

2. Oracles: This pool relies on a rate provider for wstETH which Balancer has been using already for awhile. See here.

3. Audits: See here.

4. Centralization vectors: See here for information on this.

5. Market History: See here.

6. Value: Balancer will earn the protocol fee on wstETH yield. By paring with wstETH we encourage more wstETH trading activity and since wstETH/ETH is one of our largest pools, any increase in trading activity will make wstETH liquidity even more profitable for us.
