    unquote resource id to support slash in it

    Swift related meters can generate samples with special resource id
    which contains slash, such as: 29f809d9-88bb-4c40-b1ba-a77a1fcf8ceb/glance.
    If we query such resource directly, pecan will return 404 error,
    but even end user encodes that special slash, we cannot response too.

    This patch unquotes resource id in case it contains special characters.

    Note that end user needs to use %252F to escape % character as well
    to avoid pecan map slash to path delimiter.
