[7.x] Convert most OSS plugins from integTest to [yaml | java]RestTest or internalClusterTest (#59444) (#60343)

For all OSS plugins (except repository-* and discovery-*) integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.

This commit does NOT convert the discovery-* and repository-* since they
are bit more complex then the rest of tests and this PR is large enough.
Those plugins will be addressed in a future PR(s).

This commit also fixes a minor issue that did not copy the rest api
for projects that only had YAML TEST tests.
