Description of problem: The package mkfs.xfs is missing from the AMI on AWS. This makes cloud-init more difficult as it will not allow for cloud-init to create a xfs partition on assigned storage. 


Version-Release number of selected component (if applicable):
ami-2a5d9a47

How reproducible:
Launch a new instance and use the following cloud-init/user-data

#cloud-config
cloud_config_modules:
- disk_setup
- mounts

fs_setup:
- label: etcd_storage
  filesystem: xfs
  device: /dev/xvdc
  partition: auto

runcmd:
- mkdir -p /var/lib/etcd

mounts:
- [ /dev/xvdc, /var/lib/etcd, xfs, "defaults" ]


Steps to Reproduce:
1. Launch instance in AWS using above cloud-init
2. cat /var/log/cloud-init-output.log
3.

Actual results:

2016-09-22 03:03:20,623 - cc_disk_setup.py[WARNING]: Cannot create fstype 'xfs'.  No mkfs.xfs command

Expected results:
Filesystem is provisioned

Additional info:
The package xfsprogs needs to be added to the image. If this is added this will allow devices to be partitioned with xfs
