Remove JUnit5 org.junit.jupiter:junit-jupiter-migrationsupport dependency from codebase

[rohanKanojia]

Is your task related to a problem? Please describe

We seem to be including this dependency in most of our poms:

kubernetes-client/pom.xml

Lines 837 to 841 in c76762a

	<dependency>
	<groupId>org.junit.jupiter</groupId>
	<artifactId>junit-jupiter-migrationsupport</artifactId>
	<version>${junit.version}</version>
	<scope>test</scope>

I think it was added during JUnit5 refactor to maintain compatibility with JUnit4 @Rule, when mockserver had to be used with a @Rule. But now that we've migrated to JUnit5 extension @EnableKubernetesMockServer. This dependency should not be required.

I only see one place where we're using @Rule in a JUnit5 test, but it can easily be replaced with @TempDir JUnit5 annotation:

kubernetes-client/uberjar/src/test/java/io/fabric8/kubernetes/clnt/UberJarTest.java

Lines 49 to 50 in c76762a

	@Rule
	public TemporaryFolder folder = new TemporaryFolder();

You can find all the occurrences of this dependency by searching for junit-jupiter-migrationsupport in project.

Describe the solution you'd like

Remove all occurrences of org.junit.jupiter:junit-jupiter-migrationsupport dependency. For most places, it should be as trivial as removing the dependency from pom.

[akshayamadhuri]

@rohanKanojia after removing the org.junit.jupiter:junit-jupiter-migrationsupport dependency I got an error with the Maven test

[rohanKanojia]

@Akshaya-hub : Are you getting error in UberJarTest? You can try replacing TemporaryFolder Rule there with @TempDir annotation.
