    Make API calls in Instances view parallel
    
    In order to increase rendering speed, make
    api.nova.server_list, api.network.servers_update_addresses,
    api.nova.flavor_list and api.glance.image_list_detailed
    parallel. For admin panel also api.keystone.tenant_list
    is parallelized.

Title:
  Sequential API requests in instance list as a bottleneck

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  When loading instances list, the following API calls are executed
  sequentially

  * nova server list
  * neutron update addresses
  * nova flavor list
  * glance image list

  Only the first one really needs to be the first one, three following
  ones can be run in parallel. Currently it acts as a big bottleneck in
  environments with a lot of servers, flavours and images.
