Server list supports many more states

v0.5.2

This is a list of features currently lacking and (eventually) under development:

security groups are still broken, appear to be broken in Fog. Add -G support for security groups other than 'default'
purge only works when names match up with clients
knife openstack floating list|associate|disassociate ip|node
take either the flavor ID or the flavor name
take either the image ID or the image name
more information in knife openstack image list
get DNS names working
availability zones
filter out the *-initrd and *-kernel from 'openstack image list'. Fog -> container_format={aki|ari} or disk_format on the same params
assumption of only single floating IP (and fog uses the last as the public_ip_address)
probably other places public network is assumed that could cause issues
