Osmosis v4.0.0 - Berylium

This upgrade is a large stability upgrade to Osmosis. It brings with it faster epochs, and improved computation time for various on-chain operations, and fixes to the high gas amounts needed for bonding and unbonding txs.

The features of this upgrade are:

• Fixing gas issues for bonding and unbonding tokens (NOTE: issues at epoch of there just being super high amounts of activity may still persist, with it taking seconds for txs to get into a block)
• Removing the need for users to withdraw locked tokens once they are finished unlocking
• Adding a governance parameter for a minimum fee to create a pool.
• Implements prop 12
