Bug 2227950

Description of problem:

This is to track tekton resource creation under custom namespace. There are two possibilities:
1. Document steps needed to add tekton resources under custom namespace
2. Instead of user doing it manually we create a task that will pre-check and if missing create. 


Version-Release number of selected component (if applicable):
4.14

How reproducible:
always

Steps to Reproduce:
1.Use a custom namespace during pipeline runs
2.
3.

Actual results:
