Repeatedly re-record requests and apply refinement to the recorded requests

[pluma9]

When to re-record requests?

• Re-record the requests multiple times with different payloads during development
• Re-record the requests every once in a while to stay up-to-date with the real APIs

After recording a request, I may want to apply some refinements to it:

1. Remove headers like agent and etag
2. Remove fields from body (leaving the body pattern with a subtree of the original json body)
3. Change the matcher to partial matcher
4. Use regex for some fields

Every time I re-record the requests, I need to manually re-apply the refinements. This may get out of hand when the number of requests increases.

For 1., we can use the ExcludedHeaders setting
For 2., perhaps we can add a similar setting for body
For 3. and 4., see the below idea (The idea can be also applied to 1. and 2.)

Can we add support for request transformation (in addition to response transformation)? That is, the ability to define a template that transforms the recorded request (i.e. the .Request object in the mapping json) into the expected request. With that, we re-record the requests without performing any additional steps.

Another option is to have some kind of script for transforming a request after we record it. I believe this may work but it requires a manual step and the above idea sounds like a more streamlined way of doing this.
