Title: Add support for the encoding key to write_files

From the updated documentation included in this commit, this is now supported:

- **encoding**: The encoding of the data in content. Supported encoding types are:
- **b64, base64**: Base64 encoded content
- **gz, gzip**: gzip encoded content, for use with the !!binary tag
- **gz+b64, gz+base64, gzip+b64, gzip+base64**: Base64 encoded gzip content

```yaml
#cloud-config
write_files:
- path: /tmp/like_this
permissions: 0644
owner: root
encoding: gzip
content: !!binary |

Note: This PR also bumps the version of yaml.v1 in Godeps to support the transparent decoding of the !!binary tag
