feat(rosettarpc): Data API implementation (revamped) (#3275)

Fixed the tests by keeping Rosetta RPC server disabled by default (so TCP ports do not collide on concurrent tests execution). Will need to run nightly tests before merging

Nayduck is fixed: http://nayduck.eastus.cloudapp.azure.com:3000/#/run/293
