Displaying a wrong message in ng-launch instance

[Kenji Ishii]

APIs called when ng-launch instance modal is opened are async. Because of this, when a response time of an api is delayed user may see a wrong message.

For example about Details tab, it needs to list availability zones and we request its infomation to Server. However, some case, users may see the message "There are no Availability Zones." because that request is not still finished.

This make users confuse. We should distinguish whether there are no availability zones or just under requesting it.

    Fix the issue that a wrong message is shown in ng-launch instance

    In some case like an api response is delaying, users may see the message
    "There are no Availability Zones" in Details tab.
    Because the request to get availability zones is not still finished.
    It makes user confuse.
    This patch distinguish whether there are no availability zones or just
    under requesting it and show users a proper message.

    This matter may occur not only above case but also other tabs.
    But at the moment, this patch is addressing only Details tab because
    this tab is first one to be shown to users.
