IMPALA-8879: upgrade bootstrap for debug page to 4.3.1

Also upgrade DataTables to 1.10.18 at the same time..

They were obtained from https://datatables.net/download/
and https://getbootstrap.com/docs/4.3/getting-started/download/.

Included the version number in the css and js filenames to
avoid potential issues with stale versions being cached
(I got tripped up by this).

I had to do some additional work to get the UI to look right
after the upgrade:
* added additional style classes to HTML elements for nav and
  breadcrumb styles - these are required in bootstrap 4.
* added styling for plan visualisation graph for it to
  appear similar to the old graph.
* Added styling for <pre> to get box around text.

Testing:
Manually clicked through the web UI to see if anything looked
wrong or didn't function correctly.
