Apollo refresh auth token link. It tries to refresh the user access token on the fly when API throws out an UNAUTHENTICATED error. If multiple requests fail at the same time, it queues them to re-try them later if we are able to get a new access token, otherwise we log out the user and redirect him to the login page.

	import { onError } from 'apollo-link-error';
	import { Observable } from 'apollo-link';

	import { buildAuthHeader } from 'utils/requests';
	import { getProvider as getGlobalProvider } from 'GlobalState';

	let isFetchingToken = false;
	let tokenSubscribers = [];
	function subscribeTokenRefresh(cb) {
	tokenSubscribers.push(cb);
