Data filtering

Use a data string filtering component in every record list so users can easily filter records on long lists.

Only filters the content on the current view, it doesn't perform a search.

<div class="input-group input-group-search">
  <input type="search"
    class="form-control"
    placeholder="Filter…"
    ng-model="vm.searchString">
  <span class="input-group-addon">
    <i c8y-icon="filter" ng-show="vm.searchString.length === 0 || !vm.searchString "></i>
    <i c8y-icon="times" class="text-muted ng-hide" ng-show="vm.searchString.length > 0" ng-click="vm.searchString = ''"></i>
  </span>
</div>
