Story (Required)

As a Primaza Administrator, I would like to have ClusterEnvironment healthchecks so that I know if target clusters are reachable and well-configured

Background (Required)

As defined in the Primaza architecture document, we need to define healthchecks for ClusterEnvironments.
See epic for arch document link.

Glossary

See glossary in architecture document

Out of scope

• Reachability and Permission checks (they are implemented in APPSVC-1272)

In Scope

• Perform a check on each worker cluster every x seconds.

Approach(Required)

Healthchecks should be implemented in Primaza's controller. If needed, we can move it later in a different application.

Check each worker cluster status in a timely fashion.
The amount of seconds to wait between checks should be retrieved from an environment variable, and defaulted to 600 seconds.
You can use concurrency to reduce time needed for checking all clusters, but it's not mandatory for now.

ClusterEnvironment status must be updated with respect to healthcheck result. Both status.state and status.conditions must be updated.

Demo requirements(Required)

A great demo would demonstrate healthchecks on clusters in different conditions. Clusters status should vary and healthchecks should show that.

Acceptance Criteria

• Development
  Primaza checks whether target cluster are reachable and well-configured in a time-based fashion

• QE
  There are test cases for healthchecks result being displayed in ClusterEnvironment conditions

• Docs
  The docs page about ClusterEnvironment is updated with Healthcheck description
  Update architecture document with any changes while implementing
