And convert the corresponding function expressions to arrow style
while we’re here.

Steve Howell d258a27a79 refactor: Extract filter_taken_users. 
We will take advantage of this in a few more
commits.

Steve Howell f0d101edf5 pills: Streamline input pills (for user groups). 
The main point of this change is to streamline the core
code for input pills, and we use also modify user groups.

The main change to input_pill.js is that you now
configure a function called `create_item_from_text`, and
that can return an arbitrary object, and it just needs
a field called `display_value`.

Other changes:
    * You now call `input.create(opts)` to create the
      widget.
    * There is no longer a cache, because we can
      write smarter code in typeahead `source` functions
      that exclude ids up front.
    * There is no value/optinalKey complexity, because
      the calling code can supply arbitrary objects and
      do their own external data management on the pill
      items.
    * We eliminate `prependPill`.
    * We eliminate `data`, `keys`, and `values`, and just
      have `items`.

Greg Price 5b73c54a74 docs: Push all extraneous level-1 headings inward. 
This prevents internal headings like "Basic Example" from appearing in
the left nav at the same level as all the various subsystems.

David Rosa Tamsen 7072fa5b37 docs: Reorganize developer docs to improve navigation. 
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.

This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.

Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).

Fixes #5265.
