Spaces at the beginning and end of strings not allowed

[Vish Ishaya]

There is no way to create a configuration string that has a space at the beginning or end because we strip() the input. This means that certain default options cannot be replicated in the config file. For example, the following option in nova cannot be modified properly as it requires an eol space for proper output:

   cfg.StrOpt('instance_format',
               default='[instance: %(uuid)s] ',

We should allow for options (at least string options) to be quoted so we can handle bol and eol spaces.
