ContractDetails.owner is never read
The `ContractDetails` struct used by `Ingress` contracts has an `owner` field that is written to, but it is never read.\\n```\\nstruct ContractDetails {\\n    address owner;\\n    address contractAddress;\\n}\\n\\nmapping(bytes32 => ContractDetails) registry;\\n```\\n
Resolution\\nThis is fixed in PegaSysEng/[email protected]d3f505e.\\nIf `owner` is not (yet) needed, the `ContractDetails` struct should be removed altogether and the type of `Ingress.registry` should change to `mapping(bytes32 => address)`
```\\nstruct ContractDetails {\\n    address owner;\\n    address contractAddress;\\n}\\n\\nmapping(bytes32 => ContractDetails) registry;\\n```\\n
