* Add: arrow-parens eslint rule

* Attempt ENS resolution on any valid domain name (MetaMask#8059)

ENS currently supports a variety of tlds in addition to `.eth`, and
more will be supported in the future. Rather than hard-code a list of
supported ENS tlds, all valid domain names will now be interpreted as
potential ENS addresses in our address input component.

Closes MetaMask#7978

* Remove unused sinon sandboxes (MetaMask#8063)

These sandboxes were created, then not utilized at all.

* Enable core ESLint no-mixed-operators rule

* Update redux-related dependencies (MetaMask#8068)

* Add optional chaining (MetaMask#8052)

* Add plugin-proposal-optional-chaining

* Use optional chaining to provide error fallback

* Remove redux-test-utils dependency (MetaMask#8070)

* Remove usages of redux-test-utils
* Remove redux-test-utils dependency

* Use react-redux@7.2.0 (MetaMask#8069)

* Implementation encrypt/decrypt feature (MetaMask#7831)

Implement `eth_decrypt` and `eth_getEncryptionPublicKey`. This allows decryption backed by the user's private key. The message decryption uses a confirmation flow similar to the messaging signing flow, where the message to be decrypted is also able to be decrypted inline for the user to read directly before confirming.
