Title:
  openstack server list is very slow and makes too many HTTP connections

Status in python-openstackclient:
  New
Status in python-openstackclient package in Ubuntu:
  Triaged

Bug description:
  'openstack server list' does an obscene number of HTTP requests (228
  in my case) and as a result is very slow compared to 'nova list'.

  By comparison, the 'nova list' command does 6.

  $ openstack --debug server list > openstack.log 2>&1

  real  1m48.731s
  user  0m4.702s
  sys   0m0.648s

  $ time sstack nova --debug list >nova.log 2>&1

  real  0m3.726s
  user  0m1.192s
  sys   0m0.105s

  $ grep "GET call" nova.log | wc -l
  6
  $ grep "GET call" nova.log
