Resolve "Fix Incomplete Kubernetes Cluster Status List"

What does this MR do?

On the Kubernetes cluster index page, there is an icon that displays a circle with a color and tooltip that displays that status of the cluster.

There is an issue with the status list.

The issue is still being investigated, so in the meantime we will remove the icon altogether.

Also, there is a loading icon that displays when the status is 'Deleting'. It has been requested that we also display a loading icon when the status is 'Creating'.

Testing Instructions

Ideally you already have a Kubernetes cluster set up. If not, follow these instructions to fake some clusters:

1. Update the fetchClusters method in the actions file:

const clusterList = [
  {
    name: 'My Cluster 1',
    environment_scope: '*',
    cluster_type: 'group_type',
    provider_type: 'gcp',
    status: 'creating',
    nodes: null,
  },
  {
    name: 'My Cluster 2',
    environment_scope: 'development',
    cluster_type: 'project_type',
    provider_type: 'aws',
    status: 'deleting',
    nodes: [{ usage: { cpu: '246155922n', memory: '1255212Ki' } }],
  },
  {
    name: 'My Cluster 3',
    environment_scope: 'development',
    cluster_type: 'project_type',
    provider_type: 'none',
    status: 'authentication_failure',
    nodes: [
      { usage: { cpu: '246155922n', memory: '1255212Ki' } },
      { usage: { cpu: '307051934n', memory: '1379136Ki' } },
    ],
  },
];

const apiData = {
  clusters: clusterList,
  has_ancestor_clusters: false,
};

export const fetchClusters = ({ state, commit }) => {
  commit(types.SET_CLUSTERS_DATA, { data: apiData, paginationInformation: {} });
  commit(types.SET_LOADING_STATE, false);
};

2. Add the js-clusters div to the top of the index file:

.clusters-container
  #js-clusters-list-app{ data: { endpoint: clusterable.index_path(format: :json) } }
  - if @clusters.empty?
    = render "empty_state"
