(Provenance Search Events - add feature to allow inverse query) One case this will come in handy is if a particular flowfile has an issue and goes in circles through processors and ends up emitting a lot of provenance making it hard to follow other flowfiles. This feature will allow users to query for all provenance except for the uuid of the problematic flowfile. This can also be used for any indexed field or attribute as well. This has been compiled and tested on java 8 and java11 for all 4 provenance repository implementations for both indexed fields and indexed attributes The only "real" code changes were made to LuceneUtil.java (to handle WriteAhead, EncryptedWriteAhead and Persistent Provenance Repostories) and VolatileProvenanceRepository.java The rest are just involved in propagating the ability to query the "NOT" option for a given user entered provenance search value from the gui to the backend query. Thank You, Nissim Shiman
