Packaging up a number of content collection fixes.

[alan-cole]

Motivation and Context

As there's been a number of fixes for the content collection front-end, spanned across 3 unique PR's, this PR is a chance to tackle implementing them into the core content collection library so they can be QA'd and merged in a single go.

JIRA issue: No ticket.

Changed

The PRs this ticket includes are:

#1118

• Fix issue with Content Collection not using ES total objects (only worked with total numbers).
• Display component to properly default to card. This will fix issue where if no value set, cards would not appear in a grid.
• Implement the interface.filters.defaultStyling option to automatically set the column classes on the exposed filters.
• Add RplMarkup support for description.

#1150

• Added a new schema property check to hide counts in filter select lists. New property is elasticsearch-aggregation-show-count

#1176

• Fixed internal sort and added clear hierarchy of external over internal if both set.

Sorry this has sat here so long @alan-cole. Without any tests is hard for us to know if this breaks anything and manual QA is resource intensive. We are working on some e2e tests to cover this.
