Create deployment scope detection mechanism for index generator

/area registry

Which functionality do you think we should add?

Why is this needed? Is your feature request related to a problem?

Allows index server to serve clients an index schema, /v2index response, which contains new field(s) for getting the deployment scope (innerloop/outerloop) of a stack.

Detailed description:

Since the release of devfile 2.2.0, more and more stack under the devfile registry have been adopting outerloop support within the newest versions. However, with there being certain stacks which have not adopted outerloop support yet along with legacy stack versions which would not either comes no guarantee that all devfile 2.2.0 stacks will support outerloop.

In addition, there can also exist new stacks going forward which only support outerloop as well.

With the introduction of new field(s) under the index schema which indicates the deployment scope of the stacks, this can make it easier for clients to filter to the scopes they need.

Describe the solution you'd like

1. A new field or fields which indicate the deployment scope of stacks (tracking this in Add new field which indicates the deployment scope of stacks/samples #1321)
2. A function for checking if a Kubernetes or OpenShift deployment spec exists
3. A function for detecting the deployment scope and to fill in this information during generation of the index
4. Unit test cases for these functions

Innerloop Detection Example

hasInnerloopCommandGroups := commandGroups["run"] || commandGroups["debug"]
hasInnerloopComponents := false

for _, component := range components {
  if component.Container != nil {
    hasInnerloopComponents = true
    break
  }
}

if hasInnerloopComponents && hasInnerloopCommandGroups {
  deploymentScopes["innerloop"] = true
}

Describe alternatives you've considered

The alternative is to advise clients on how to perform deployment scope detection on the client side of the devfile response from the index server.

Additional context

Blocked by #1322 for detail on implementation of the detection mechanism and by #1321 for the new deployment scope field.

[michael-valdron]

#959 will include the addition of the deployment scope filter on completion of this issue.

[michael-valdron]

Based on #1321 & #1322 refinement and sizing this issue will need to be resized to its current details and scope. Moved out of sprint and rescheduled for an upcoming refinement call.

Still needed and waiting on #959 to be resolved.
