Provide a way to cache the PipelineTestHelper and dependent libraries

[jacobfederer]

The PipelineTestHelper does a lot of heavy lifting e.g. loading a library from various sources. Since the library content doesn't change during the test execution it would be good to provide a way to cache this helper and it's dependent libraries to speed up the test execution and reducing the I/O effort.

You can call the BasePipelineTest#setUp method in the per class initializer of your test runner.
For example if you are using JUnit you can call the setUp method in your @BeforeClass method as in

class PipelineJobTest extends BasePipelineTest {
    
    @BeforeClass
    void initTests() throws Exception {
        super.setUp();
    }

Unfortunately this is not possible since @BeforeClass requires the method to be static. This is caused by the fact that every @Test method will be executed in a separate instance of the referenced test class.

We have our shared library inside a git repository and we are using the .retriever(GitSource.gitSource(...)) approach to load the shared library... and we have >1300 jobs to tests. If that's true it means that we perform a serious DDOS against git server.

Any workarounds?
