remove trailing line, causing every deployment to update the file and…

Prefer "pkgs" rather than "names" when using pkg.installed

"names" makes a separate call to the package management frontend to
install each package, whereas "pkgs" makes just a single call so that it
improves performance.

Add linux.storage.loopback state

cpu governor

This state allows to configure loopback device(s). This isn't meant to
be used in production but offers a cheap way to test Cinder with LVM
volumes.

Parameter purge_hosts will enforce whole /etc/hosts file, removing entries
that are not defined in model except defaults for both IPv4 and IPv6 localhost
and hostname + fqdn.

It's good to use this option if you want to ensure /etc/hosts is always in a
clean state however it's not enabled by default for safety.
