Features for set_code_hash pattern

[Artemka374]

• AdminUpgradeableImpl : This contract will manage who can upgrade a contract,
  allowing roles to be separated between the owner of the contract and the administrator
  of the upgradeability features. Unlike Solidity and the Proxy Pattern, where the storage
  layouts of the proxy and the implementation are defined separately (even though the
  storage itself is the same), using set_code_hash directly changes the code of a
  contract at a given address, meaning both the storage layout and storage are shared and
  defined in the implementation contract. By implementing an AdminUpgradeableImpl
  contract, it becomes possible to easily separate the roles of the contract owner and the
  administrator of upgradeability.
• An upgradeAndCall function: This permissioned function allows the caller to both
  upgrade the code of the contract and call a function and/or the constructor to initialize
  new variables introduced in the newest implementation in the same transaction.
• An Initialize contract: This contract sets the initializing function mentioned above
  to be callable only once.
