Artem Goncharov 69801f268f Wait for deleted server to disappear from results 
When we delete server wait for it to completely disappear from the
results (Nova returns it for some time with the 'DELETED' state). Since
tests (and actually also users) not able to really cope with this wait
for server to be gone completely.

short_description: Create/Delete Compute Instances from OpenStack
author: OpenStack Ansible SIG
description:
- Create or Remove compute instances from OpenStack.
options:
auto_ip:
description:
- Ensure instance has public ip however the cloud wants to do that.
- For example, the cloud could add a floating ip for the server or
attach the server to a public network.
- Requires I(wait) to be C(True) during server creation.
- Floating IP support is unstable in this module, use with caution.
- Options I(auto_ip), I(floating_ip_pools) and I(floating_ips) interact
in non-obvious ways and undocumentable depth. For explicit and safe
attaching and detaching of floating ip addresses use module
I(openstack.cloud.resource) instead.

description:
- When I(auto_ip) is true and this option is true, the I(auto_ip) code
will attempt to re-use unassigned floating ips in the project before
creating a new one. It is important to note that it is impossible
to safely do this concurrently, so if your use case involves
concurrent server creation, it is highly recommended to set this to
false and to delete the floating ip associated with a server when
the server is deleted using I(delete_ips).
