New Generic indexing command os we don't have to have one for solr, and slq engine in the future, for now the old once are still in there so doc is not invalidated. However we should maybe create a task to update this and pass this to QA for now.
For use see:
php app/console ezplatform:reindex --help
(ref. https://jira.ez.no/browse/EZP-26098, done as a separate task so as not to block QA)
