Add logs for createProxy and upgradeProxy

[spalladino]

With DEBUG enabled, there are no logs when a createProxy or upgradeProxy operation is run.

@spalladino What kind of logs do you mean? Since there is already logging around the proxy admin and implementation contract deployments.

@frangio if the proxy admin and implementation contract are already deployed, then no logs are shown when createProxy or upgradeProxy are called. I'd expect a log entry that lets me know that either a Proxy is being deployed, or an upgradeTo is being called.
