Add query param in list apps call which enables default pagination

After adding default pagination (https://github.com/cdapio/cdap/pull/15745) to list apps which are enabled mainly for boosted instances currently, the form of response changed from array to object. In many places in UI, the paginated response is not handled. Eg:
Case 1: In service status page, namespaces/system/apps API is called which doesn’t handle the paginated response.
Case 2: When we open replication tab from home page after enabling CDC accelerator, namespaces/default/apps?artifactName=delta-app API is called which lists replication pipelines. Here, the UI doesn’t handle paginated response.

To fix this we will add a query param enableDefaultPagination in list apps call. By default it will be false. When true, it will add default pagination during list apps.
