Title:
  When keystone is slow to respond: getting user fails

Status in puppet-keystone:
  Confirmed
Status in tripleo:
  Confirmed

Bug description:
  To test if an user exists we check the keystone db by using

      openstack show user 'foo' ...

  If the user doesn't exists then we get an error.  The usual retry of
  openstack lib would imply that we wait the full request_timeout to get
  this.  This is currently ~170s.  So 170s times the number of user
  in the catalog!

  To overcome this a the call is wrapped inside a no retry outer
  function[1]

  The problem is that on very slow platform legit timeout can occur,
  this is especially true for CI.  Here is an example of such failure:

      Error: /Stage[main]/Keystone::Roles::Admin/Keystone_user[admin]:
  Could not evaluate: Command: 'openstack ["user", "show", "--format",
  "shell", ["admin", "--domain", "default"]]' has been running for more
  then 20 seconds (tried 0, for a total of 0 seconds)
