Current functionality on new design over Rest-EPP

[vohmar]

new design: https://github.com/internetee/registrar-css
repp doc: https://internetee.github.io/repp-apidoc/#introduction

expected functionality:

• poll messages
• domain listing and domain object requests (domain info, check, renew, update, transfer, create, delete)
• contact listing and contact object requests (info, check, update, create, delete)
• billing - balance, add credit, invoice listing, account activity
• xml_console - xml console is nor relevant in repp context but similar way to see raw server responses might be helpful for troubleshooting
