This changes the API codegen template (controller-api.mustache) to simplify some names. When this package was created, most APIs "forked" to either a Grafana backend implementation or a "Lotex" remote implementation. As we have added APIs it's no longer the case. Provisioning, configuration, and testing APIs do not fork, and we are likely to add additional APIs that don't fork.
This change replaces {{classname}}ForkingService with {{classname}} for interface names, and names the concrete implementation {{classname}}Handler. It changes the implied implementation of a route handler from fork{{nickname}} to handle{{nickname}}. So PrometheusApiForkingService becomes PrometheusApi, ForkedPrometheusApi becomes PrometheusApiHandler and forkRouteGetGrafanaAlertStatuses becomes handleRouteGetGrafanaAlertStatuses
It also renames some files - APIs that do no forking go from forked_{{name}}.go to {{name}}.go and APIs that still fork go from forked_{{name}}.go to forking_{{name}}.go to capture the idea that those files a "doing forking" rather than "are a fork of something."

What
This aims to define the unified alerting API as code. It generates OpenAPI definitions from go structs. It also generates server/route stubs based on our documentation.
Running
make - regenerate everything - documentation and server stubs.
make serve - regenerate the Swagger document, and host rendered docs on port 80. view api
Requires
Why
The current state of Swagger extraction from golang is relatively limited. It's easier to generate server stubs from an existing Swagger doc, as there are limitations with producing a Swagger doc from a hand-written API stub. The current extractor instead relies on comments describing the routes, but the comments and actual implementation may drift, which we don't want to allow.
Instead, we use a hybrid approach - we define the types in Golang, with comments describing the routes, in a standalone package with minimal dependencies. From this, we produce a Swagger doc, and then turn the Swagger doc back into a full-blown server stub.
Stability
We have some endpoints that we document publically as being stable, and others that we consider unstable. The stable endpoints are documented in api.json, where all endpoints are available in post.json.
To stabilize an endpoint, add the stable tag to its route comment:
// swagger:route GET /api/provisioning/contact-points provisioning stable RouteGetContactpoints
