### What is this PR for? This PR has for goal to allow the user to search through the code in all the paragraphs *and notebook names* in all the notebooks It add a simple 'search bar' to the nav-bar of Zeppelin WebApp, and an in-memory fulltext search index of paragraphs to the backend. The search is pretty basic now, fine-tuning it for better search over all types of source code will be a subject of further work. ### What type of PR is it? Feature ### Todos * [x] - Fix typos 💃 b853aa6 * [x] - fix js issue in js console felizbear 29da337 * [x] - update index on paragraph CRUD: - [x] Read (initial work) - [x] Create\Delete 825b266 - [x] Update e915a69 - [x] Delete paragraph * [x] - add license to zeppelin-distribution/src/bin_license/LICENSE (backend for lucene, not sure about angular-resource as it is part of the AngularJS codebase, but will add just in case) c00b516 * [x] - add missing Apache headers ded9c3b felizbear 29da337 * [x] - fix CI (~~was failing RAT on zengine Too many files with unapproved license: 2~~, now flacky integration test AKA [ZEPPELIN-510](https://issues.apache.org/jira/browse/ZEPPELIN-510)) * [x] - index notebook names e80c3e5, felizbear 29da337 * [x] - make NotebookRepoSync.sync() package private again 5a18bc8 * [x] - NPE on persisting changes of existing notebook * [x] - reduce log verbosity ### Is there a relevant Jira issue? https://issues.apache.org/jira/browse/ZEPPELIN-501 ### How should this be tested? Outline the steps to test the PR here. ### Screenshots (if appropriate)   ### Questions: * Does the licenses files need update? Yes, added to license files * Is there breaking changes for older versions? No * Does this needs documentation? Yes This work is a collaboration with felizbear who contributed major parts of the frontend changes.
