[BIP-315] Add Single Recipient Gauge to Checkpointer

https://github.com/BalancerMaxis/multisig-ops/pull/232

Motivation

The recent release of the L2 gauge checkpointer for automating the bridging of BAL rewards can also be used to automate the distribution of BAL to single recipient gauges like veLIT and veUSH. In order for this to function properly the factory to create single recipient gauges must be added to the gauge adder v4.

Specification

If approved, the DAO Multisig 0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f will initiate a transaction to interact with the Authorizer 0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6 calling grantRoles with the following arguments:

roles: [0x2960d085c4c968d7cad55c0da3f97014525b948fdce990ecaef4e832b5f0b151,0x3f44776af02a9227991da37715b44e45db40735e216b3ab33144859bb6737166]

These correspond to the roles for calling addGaugeType and setGaugeFactory on the Gauge Adder v4, verifiable here.

address: 0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f

This is the address for the DAO Multisig to allow it to call the above functions.
