Recovery setup: deploy Recovery master copy and integrate with AddUser

[abhayks1]

Below are the steps:

• Deploy Delayed Recovery MasterCopy in UserSetup: lib/setup/User.js.
• Deploy proxy for "Delayed Recovery contract". The method can go to lib/helper/User.js.
• Integrate Recovery module with createUserWallet method. Below how the current createUserWallet looks like:

 createUserWallet(
    owners,
    threshold,
    to,
    data,
    sessionKeys,
    sessionKeysSpendingLimits,
    sessionKeysExpirationHeights,
    txOptions
  )

to, data argument of createUserWallet needs to integrate with delayed Recovery module.

LGTM, it's a big ticket, so some additional notes:

• Deploy Delayed Recovery MasterCopy in UserSetup: lib/setup/User.js.

we additionally need Gnosis' CreateAndAddModules.sol to be deployed, so a complete list of deployments in UserSetup (please correct) is:

• UserWalletFactory (done)
• GnosisSafe as MasterCopy (done)
• TokenHolder as MasterCopy (done)
• DelayedRecovery as MasterCopy
• CreateAndAddModules, a helper contract

[benjaminbollen]

• Deploy proxy for "Delayed Recovery contract". The method can go to lib/helper/User.js

this is done by the helper contract CreateAndAddModules, so it does not need to be explicitly deployed. Rather the address of the master copy of DelayedRecovery will be passed in in data of createUserWallet / GnosisSafe.setup()

Wrt the parameters to and data, it is my understanding (but this probably needs scrutiny) that:

• to is the address of the CreateAndAddModules helper contract
• data = <lenPrefix><A>

where A = abi.encodeWithFuncSelector("createProxy", addressMCDelayedRecoveryModule, B)
and B=abi.encodeWithFuncSelector("setup", paramsDelayedRecoverySetup)

so these can be taken together in one PR or made into separate tickets&PRs
