[stellarmagnet]

@srwadleigh can you deploy the erc20-watcher and address-watcher code in this repo so it's running against our Rinkeby node?

• erc20-watcher would be at https://erc20.vdb.to
• address-watcher would be at https://addr.vdb.to
• Whenever you go to either of the URLs, it should expose the GraphiQL interface
• Add both watchers to https://status.vdb.to/ and https://github.com/vulcanize/ops/blob/master/docs/vulcanize-hosts.md

• Also needs the latest of ipld-eth-server once @arijitAD has added tests and merged getLogs API changes to return txHash, make contract arg optional. cerc-io/ipld-eth-server#81.
• We need to start exposing the port/endpoint for the inbuilt ipld-eth-server GQL server too
• A recent large PR that landed on ipld-eth-server also has changes to command line params by Ramil. We should coordinate on the deployment with him to figure out new cmd options that correspond to the older ones.
