[GIP-25] Remove Withdrawal Fee

Motivation

Remove the 1% withdrawal fee on the pools side.

Summary

The concept of a withdrawal fee was never supposed to stay for long, it was only there to prevent fluctuations during the first weeks of usage. Fluctuations refer to the fact when pools only have $2-4M and large withdrawals can shift borrow rates up-down too much. That was an inconvenience. Not anymore.

While this is in no way sticky liquidity, everyone is entering pools under assumption 1 that the fee won’t be there. Therefore, a few weeks into V2 full usage, withdrawal fee shall be removed fully. At that point, LPs can decide whether they want to stay for the organic APYs and the proper LM program — or leave.

This was never a sustainable revenue-making source for the protocol.
