Problem

Relating to test error reported in https://issues.liferay.com/browse/LPS-145831 and the test itself https://github.com/liferay/liferay-portal/blob/master/modules/apps/portal-search/portal-search-test/src/testIntegration/java/com/liferay/portal/search/indexer/test/IndexerPostProcessorRegistryTest.java indexer post processors should not to be shipped with the platform.

Negative Consequences

Test errors in various modules (see linked).

Acceptance Criteria

1. IPP tests are passing
2. Migrate the logic of ContentLengthIndexerPostProcessor to be a ModelDocumentContributor in portal-search Introduced in LPS-145828
3. Delete ContentLengthIndexerPostProcessor
4. Add wiki "versionCount" in WikiPageIndexer Done in LPS-145828
5. Add document library "versionCournt" in DLFileEntryModelDocumentContributor Done in LPS-145828
6. Add Journal article "versionCount" in JournalArticleIndexerPostProcessor Done in LPS-145828

Technical Notes

ContentLengthIndexerPostProcessor relies on the the "content" field and it obtains it from the Document. As the order in which *ModelDocumentContributor/s are processed is not fixed, this has to be considered when refactoring.
