[ZEPPELIN-2420] Slow notebook listing in navbar
[ZEPPELIN-2420] Slow notebook listing in navbar

### What is this PR for?

Notebook listing is slow as you can see in the screenshot below.

The problem was,

- angular-bootstrap was updated to 2.5
- then, `dropdown-*` directives should be converted into `uib-dropdown-*`
- otherwise, changes in angular controller scope values will not affect on the directives even though events are fired. (`show.bs.dropdown`, `hide.bs.dropdown`)

```
  function initNotebookListEventListener() {
    angular.element(document).ready(function() {
      angular.element('.notebook-list-dropdown').on('show.bs.dropdown', function() {
        $scope.isDrawNavbarNoteList = true;
      });

      angular.element('.notebook-list-dropdown').on('hide.bs.dropdown', function() {
        $scope.isDrawNavbarNoteList = false;
      });
    });
```
