This helper adds a datepicker to all `js-access-expiration-date`
elements. If that element is a child of a `clearable-input` element and
has a sibling `js-clear-input` element, then it will show a working
clear button to the right of the input field.

Also updates protect branch list

1. Reuse the same dropdown component that we used for updating these
   settings (`ProtectedBranchesAccessSelect`). Have it accept options
   for the parent container (so we can control the elements it sees) and
   whether or not to save changes via AJAX (we need this for update, but
   not create).

2. Change the "Developers" option to "Developers + Masters", which is
   clearer.

3. Remove `developers_can_push` and `developers_can_merge` from the
   model, since they're not needed anymore.

1. Move to dropdowns instead of checkboxes. One each for "Allowed to
   Push" and "Allowed to Merge"

2. Refactor the `ProtectedBranches` coffeescript class into
   `ProtectedBranchesAccessSelect`.

3. Modify the backend to accept the new parameters.
