[test] Unit test speed improvement

[Rohanraj123]

Problem Statement

Its just a suggestion. Improvement of unit testing speed allows to complete testing in less time. And Here's a blog that describes it clearly. Now I looked at the codebase and didnt saw any implementation of parallelism in testing. Now there might have some reason that I am not aware of ( Please let me know if any) otherwise I did implemented it in running two testcases( Test_ImageVerifyCacheDisabled, Test_ImageVerifyCacheExpiredCosign ) parallely and i think it reduced testing time.

Before:

After:

Idea is to use t.paralle() carefully where it is reliable to run test cases parallely.

Solution Description

Using t.paralle() to run test cases parallely.
