Description of problem:

When open the topology and no project is selected (the list of project of projects was shown), it automatically fetches many resources anyway.

This fetched resources are not filtered for a specific namespace, so it fetches cluster-wide for Deployments, Pods, Jobs, Routes, services, and so on.

Prerequisites (if any, like setup, operators/versions):

None

Steps to Reproduce

1. Open your browser debug tools and open the network tab
2. Open the developer perspective, select Topology
3. If you have selected/favorited a Project previously select "All Projects" from the project dropdown and refresh your browser

Actual results:

See many api calls like

/api/kubernetes/apis/apps.openshift.io/v1/deploymentconfigs?limit=250
/api/kubernetes/apis/apps/v1/deployments?limit=250
/api/kubernetes/api/v1/pods?limit=250
...

which return data from all namespaces.

Expected results:

Topology do not fetch resources from all namespaces if "All projects" is selected (and no topology was shown)

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

4.7 master (commit 3fdbb93c40a17065613c949653e9d02f7e52a5ad)
tested also on 4.7.0-0.nightly-2020-12-04-013308

Additional info:

Side effect is an error in the reconcile logic. Maybe its an good moment to check this also. See first comment.
