* Adds searching and filtering for nodes on topology view
* Lintfix and changelog
* Acceptance tests for topology search and filter
* Search terms also apply to class and dc on topo page
* Initialize queryparam values so as to not break history state
This fixes a couple bugs
1. Overreporting resources reserved due to counting terminal allocs
2. Overreporting unique client placements due to uniquing on object refs
instead of on client ID.
