Use groups to determine distro packages to install

Use the groups defined in swift_services to determine which distro
packages to install onto hosts instead of installing all distro service
packages on all swift hosts.

The 'swift-plugin-s3' package has also been removed from debian's
package list. s3api should be configured through swift middleware instead.
