Function: earmarkRewards(uint256 _pid)

Responsible for collecting the CRV from gauge and then redistributing to the correct place. Pays the caller a fee to process this.

The function is a thin wrapper for _earmarkRewards(_pid), which claims CRV from the staker, transfers idle CRV in the Booster to the treasury, and finally transfers it to the LP provider reward contract. Incentives (fees) are paid to the caller and the lockers reward contract.
