Some string values in nova.conf.sample need to be quoted

[Mark McLoughlin]

For example, the default for instance_uuid_format is '[instance: %(uuid)s] ' but unless the value is quoted in nova.conf, we loose the trailing space.

    Ensure log formats are quoted in sample conf

    Fixes bug #1040583

    This ensures the sample conf has:

      # instance_format="[instance: %(uuid)s] "

    rather than:

      # instance_format=[instance: %(uuid)s]

    Fix suggested by Vish.
