[ProxyAdmin] Upgrade implementation of multiple proxies with one tx

See original GitHub issue

🧐 Motivation

I have 2 upgradable smart contracts that trust and interact with each other. I want to upgrade both of them in a way that changes their interaction API.

Upgrading them one by one will cause the downtime of the system when first contract is upgraded and second one is not. I don’t see a way to perform such operation even though proxies are owned by the same ProxyAdmin contract.

📝 Details

contract ProxyAdmin {
  function upgradeAll(TransparentUpgradeableProxy[] proxies, address[] implementations) public virtual onlyOwner {
    ... 
  }
}

You might want to do

contract ProxyAdmin2 is ProxyAdmin, Multicall {}

using the new multi-call utility.
