[ENS] Support ENS resolution for main net

[christopherdro]

The geth client for bzz.network currently runs on Ropsten testnet. Most public swarm gateways use mainnet for ENS resolution and we've been seeing reports of users having issues using bzz.network with .eth domain extensions.

The plan here is to support both main and test net since it's possible to register .eth and .test domains on Ropsten.

• [x] Bump Geth client to 1.8.3
• [x] Create new account/wallet on mainnet
• [x] Create new k8 namespace with Geth running on main net
• [x] Point new namespace to bzz.network
• [x] Add ropsten.bzz.network as new endpoint for test.bzz.network

Follow up:

• [ ] Create basic index.html for landing page
• [ ] Update tags on EFS
• [ ] Add size limit to file uploads

• A new geth client @1.8.3 is running in namespace main and is serving on bzz.network/geth.
• I've left the old test pods in the namespace `default.
• bzz.network/bzz* are pointing to the swarm pods in namespace default.
• ropsten.bzz.network is up and we'll keep test.bzz.network for the time being
