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.

	// character is a dot.
