Topic template extension maintenance (#2022)

Browse Source 
* Topic templates: Ensure parameter values are checked for wildcard

* Topic templates: Complement extension methods

- add template.BuildMessage()
- add subscribeOptionsBuilder.WithTopicTemplate()

* Topic templates: switch some samples to use a topic template

The changes should be self-explanatory and are
intended to provide more examples.

* Topic templates: add README
