Daniel Koch 8c0e8354bf Add "virtio" and "private_networking" options for DigitalOcean droplets 
The dopy manager defaults to False for virtio, but the DigitalOcean web interface defaults to True, which is a pretty safe default and sensible considering the performance gains.

Private networks are a new feature currently available only in the NYC2 region as of Oct 2, 2013.

NOTE: dopy >= 0.2.2 is required for these options to work.

module: digital_ocean
short_description: Create/delete a droplet/SSH_key in DigitalOcean
description:
- Create/delete a droplet in DigitalOcean and optionally waits for it to be 'running', or deploy an SSH key.
version_added: "1.3"
options:
command:
description:
- Which target you want to operate on.
default: droplet
choices: ['droplet', 'ssh']
state:
description:
- Indicate desired state of the target.
default: present
choices: ['present', 'active', 'absent', 'deleted']
client_id:
description:
- Digital Ocean manager id.
api_key:
description:
- Digital Ocean api key.
id:
description:
- Numeric, the droplet id you want to operate on.
name:
description:
- String, this is the name of the droplet - must be formatted by hostname rules, or the name of a SSH key.
unique_name:
description:
- Bool, require unique hostnames. By default, digital ocean allows multiple hosts with the same name. Setting this to "yes" allows only one host per name. Useful for idempotence.
version_added: "1.4"
default: "no"
choices: [ "yes", "no" ]
size_id:
description:
- Numeric, this is the id of the size you would like the droplet created at.
image_id:
description:
- Numeric, this is the id of the image you would like the droplet created with.
region_id:
description:
- "Numeric, this is the id of the region you would like your server"
ssh_key_ids:
description:
- Optional, comma separated list of ssh_key_ids that you would like to be added to the server
virtio:
description:
- "Bool, turn on virtio driver in droplet for improved network and storage I/O"
version_added: "1.4"
default: "yes"
choices: [ "yes", "no" ]
private_networking:
description:
- "Bool, add an additional, private network interface to droplet for inter-droplet communication"
version_added: "1.4"
default: "no"
choices: [ "yes", "no" ]
wait:
description:
- Wait for the droplet to be in state 'running' before returning. If wait is "no" an ip_address may not be returned.
default: "yes"
choices: [ "yes", "no" ]
wait_timeout:
description:
- How long before wait gives up, in seconds.
default: 300
ssh_pub_key:
description:
- The public SSH key you want to add to your account.
notes:
- Two environment variables can be used, DO_CLIENT_ID and DO_API_KEY.
