Tests of creating lucene indexes on regions. All tests of index creation use cases should be in
classes starting with LuceneIndexCreation*. Most tests belong in this class, except for:
<ul>
<li>Tests that use persistence are in {@link LuceneIndexCreationPersistenceIntegrationTest}</li>
<li>Tests that use offheap are in {@link LuceneIndexCreationOffHeapIntegrationTest}</li>
</ul>
