API/UI: Support custom-constrained and custom-unconstrained offerings when creating a CKS cluster #11545
Description
problem
Currently, users are unable to select the custom-constrained and custom-unconstrained offerings from the UI
And also it's not even possible from the API as we are excluding the custom offerings for cks cluster

ACS 4.21, 4.20.1
The steps to reproduce the bug
- Navigate to service offering > compute offering > create a custom-constrained and custom-unconstrained offering.
Create a custom -constrained offering od 2 cpu and 2048 ram which is the minimum requirement for a cks cluster
-
Navigate to compute > kubernetes > create cks cluster
-
The custom-constrained and custom-unconstrained are listed
...
What to do about it?
User should be able to select the custom-constrained and custom-unconstrained offerings for a cks cluster.
As it would be beneficial for the end user to specify the CPU and memory during CKS creation
A similar box related to deploy instance should be displayed during cks creation
