[fix][ci] Fix tests memory leak due to mockito-inline

[nicoloboschi]

Motivation

I noticed an increased memory usage in long-running process which run the unit broker tests. After investigating I found out the introduction of mockito-inline is the culprit.

In the documentation is specified that it this behaviour is possible and there's a way to fix it

Modifications

• Added the inline mocks cleanup between tests along with other mockito cleanups

• no-need-doc

@nicoloboschi Are the tests more flaky after this change or are there real failures? I wonder if the classloading works correctly for Mockito if reflection isn't used in a TestNG listener?

I believe they are flaky as always. I addressed the PersistentDispatcherFailoverConsumerTest in #15638

let me re-run the tests

it is better to merge #15638 before this one. then rebase and re-run the checks to see everything is green

This fix is important for stabilizing our CI. My assumption is that it would fix the strange issue #15689 where Mocks from another test are leaked into that test.
