Description of problem:

As an administrator, I want a possibility to deploy certain application on a predefined node regardless of nodeSelector set for a project. Need the following to be possible:
- normally deploy all pods in a project to some default application nodes (done via defaultNodeSelector or nodeSelector on project level)
- in some special cases, deploy the special pods IN THE SAME PROJECT to some special nodes
- it should not be possible that the normal pods land on a special node

I would recommend the use of taints/tolerations for this feature.

The special node would have the taint applied that had NoScheduleNoAdmitNoExecute operator, and only the special pod would have the toleration for that taint.  This would prevent normal pods from landing on the special node.

This bug has been identified as a dated (created more than 3 months ago) bug. 
This bug has been triaged (has a trello card linked to it), or reviewed by Engineering/PM and has been put into the product backlog, 
however this bug has not been slated for a currently planned release (3.9, 3.10 or 3.11), which cover our releases for the rest of the calendar year. 

As a result of this bugs age, state on the current roadmap and PM Score (being below 70), this bug is being Closed - Differed, 
as it is currently not part of the products immediate priorities.
