Eventing: Use apis.HTTP() instead of apis.ParseURL() in the codebase

[capri-xiyue]

Problem
In the codebase, we use apis.ParseURL() in a lot of places. As @aliok suggested, https://github.com/knative/eventing/pull/3616#discussion_r456273469, apis.HTTP() is more convenient. We can use apis.HTTP() instead of apis.ParseURL() in the codebase

Persona:
Which persona is this feature for?

Exit Criteria
Use apis.HTTP() instead of apis.ParseURL() in the codebase

Time Estimate (optional):
How many developer-days do you think this may take to resolve?

Additional context (optional)
