Merge "fix report_interval configuration"
support for managing ssh keys

This change permits provisioning ssh public and private keys as part of
creating the "nova" user.  There are no changes to the default behavior
of the module.  This changes introduces three new parameters:

- nova_public_key
- nova_private_key
- nova_shell

These changes are intended to permit configuring live migration via
qemu+ssh connections to remote hypervisors.
