Refactor vulnerability report cluster filter

What does this MR do and why?

This MR refactors the cluster filter to detangle from the simple_filter.vue and instead use the new more basic querystring_sync.vue component. The goal will make each of the filter components more flexible for customization. Please read this epic for more information > &8872 (closed).

Describe in detail what your merge request does and why.
