Schedule tkn serve cli pod also on infra node

[piyush-garg]

This will add the field in the tekton addon CRD so that nodeselector
and tolerations can be passed to tekton addon cr from config cr and
use those values in scheduling the tkn serve cli pod using already
existing transformer

Added the hash value in the installerset and if it changes, it again
read the manifest and assign to the installerset

This will fix tkn serve cli pod not getting scheduled on infra nodes
if configured in subscription and config CR
