[SWIP-22] Upgrade Vaults Factory to v2 & Reassign Restaking Functionality Ownership

In this proposal, we suggest an upgrade to the Vaults Factory smart contracts, called version 2.0.

The proposed upgrade features revamped validator management tools, improved exit queue mechanics, and custom LTV management on a per-Vault basis.

If approved, this proposal will bring support for more validator registration setups, a more efficient exit process from Vaults, and more capital utility to stakers in select Vaults when minting osETH.

Note that your approval of this upgrade does not automatically mean that all Vaults in the StakeWise network will be upgraded. The upgrade to version 2.0 is optional for every existing Vault; only the newly created Vaults will automatically use version 2.0.

This proposal also seeks to assign ownership of the new restaking functionality (still in development) to the team to allow deployment of experimental restaking Vaults for the closest partners in a permissioned manner.
