Implement Open Services Framework V1

[victorb]

Open-Registry should implement the framework specified here: https://github.com/open-services/open-services/tree/master/framework.v1

Once everything has been implemented, we can consider Open-Registry to be in the Operating phase.

There a few pieces missing to implement the V1 framework, more specifically:

• [ ] Automatic expensing (needs a invoice API from OpenCollective) and a service to perform the expensing
• [ ] Action plan in case of shutdown (financially and infrastructure-wise)
• [ ] Voting properly implemented
• [ ] Governance moved to linking to framework v1 version from Open Services
• [ ] Implement automatic infrastructure
• [ ] Implement public introspection tools (namely logging is missing)
• [ ] Add support for secrets
• [ ] Copy over issue templates
• [ ] Clearly define product focus
