Pipelines - Deployment rules - Visibility for non-Artifact Owner

[john27]

Within the deployment pipeline when you want to view a deployment rule for an artifact, you can only see it if you are the artifact owner.
The "Data source rules" and "Parameter rules" are grayed out.
However, an internal API call is made to "DiscoverArtifacts" which has the information available to see what the deployment rules are.
So in the UI we are obscuring access to the information, but it is being sent over the network.
Proposal:

1) Provide visibility to data source rules and parameter rules for workspace/pipeline admins.

2) Make deployment rules accessible through the REST API.

3) Deployment rules should also be able to be modified/created by people who are not owners of the resources
