Revert "LPS-45766 added bean analyzer as Flexjson transformer to collect information about serializable properties"

Pushed to upstream, as commits on original pull are breaking 17 tests; besides, the UI from Vocabulary/Categories is completely broken. We have been removing commit by commit, and all Igor's are not causative: only Brian's SF-commits break tests, but we also considered not leaving Igor's on master, as maybe Brian wants his changes being applied on them. cc/ @igorspasic-liferay @juliocamarero
