Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

But a variable like `user-agent` is invalid in Python.

So, by default, `Header` will convert the parameter names characters from underscore (`_`) to hyphen (`-`) to extract and document the headers.

and test another isolated pipeline from any branch. 

We'll explain everything via an example. Let's say you make some changes on your branch `myTestBranch`
(we highly recommend to name this branch without prefix and hyphen (`-`) because it's used to generate build type ID) and want to
test these changes without affecting `master`/`release` pipeline. Here are the instructions.

// 1. naming should be consistent across the controllers
// 2. use of shortcuts should be avoided, unless they are well-known non-Kubernetes shortcuts
// 3. Kubernetes' resources should be written together without a hyphen ("-")
//
// CHANGE POLICY
// The controller names should be treated as IDs.
