Migrate calls to Grafana APIs to grafana-openapi-client-go #229
Description
Story (Outcome/Output) (Required)
Our Go actions (integrate and deploy) currently make calls to the Grafana REST API using manually constructed HTTP requests. These APIs may change over time, and such breakages may not be noticed. We should use the grafana/grafana-openapi-client-go to help enforce we are making valid requests.
Context
The grafana-openapi-client-go is a Go library that is created by automatically converting the relevant Grafana OpenAPI specs to Go functions, using strong typing and correct REST paths. This will be more reliable in the future, over our ad-hoc hard-coded API calls.
Definition of Done (Required)
Any call to the Grafana API uses the go client, rather than constructing a HTTP request and decoding its responses.
Testing Plan
The existing integration suite should be applicable here, especially with query testing enabled and once a deployment integration test is implemented. In the meantime, manual testing may be required.
Dependencies (Required)
None
