Yair Fried 7eeb3445a4 Expose internal_network in os_floating_ip (#5510)
* Expose internal_network in os_floating_ip

Shade project has finally exposed this argument so now this module
matches old quantum_floatingip module's capabilities.

Use "nat_destination" term instead of "internal_network" to match shade
terminology.

* Add (private|internal)_network aliases to os_floating_ip

* Fix typo in os_floating_ip

description:
- Add or Remove a floating IP to an instance
options:
server:
description:
- The name or ID of the instance to which the IP address
should be assigned.
required: true
network:
description:
- The name or ID of a neutron external network or a nova pool name.
required: false
floating_ip_address:
description:
- A floating IP address to attach or to detach. Required only if I(state)
is absent. When I(state) is present can be used to specify a IP address
to attach.
required: false
reuse:
description:
- When I(state) is present, and I(floating_ip_address) is not present,
this parameter can be used to specify whether we should try to reuse
a floating IP address already allocated to the project.
required: false
default: false
fixed_address:
description:
- To which fixed IP of server the floating IP address should be
attached to.
required: false
nat_destination:
description:
- The name or id of a neutron private network that the fixed IP to
attach floating IP is on
required: false
default: None
aliases: ["fixed_network", "internal_network"]

wait:
description:
- When attaching a floating IP address, specify whether we should
wait for it to appear as attached.
required: false
default: false

description:
- Time to wait for an IP address to appear as attached. See wait.
required: false
default: 60
state:
description:
- Should the resource be present or absent.
choices: [present, absent]
required: false
default: present
purge:
description:
- When I(state) is absent, indicates whether or not to delete the floating
IP completely, or only detach it from the server. Default is to detach only.
