Notes

• currently if template is self contained is determined with value of Template.Self-Contained
• with introduction of multi protocol templates support for dynamic variables in template context (multi protocol execution) #3672 i think we should add method to protocol interface

type Request interface{
...
IsSelfContained() bool 
...

^ this will address minor issue in multi protocol context regarding self-contained templates

Closing as this is already supported.
