Passing list to volume filter doesn't work

[Avishay Traeger]

The db code already allows searching for a value in a list, for example, id in [id1, id2, id3]. The problem is when we get the value at the API it comes as a string and therefore the filter fails.

    Fix issue with passing lists in filters

    The Cinder db code already allows searching for a value in a list,
    for example, id in ['id1', 'id2', 'id3']. The problem is when we
    get the value at the API it comes as a string (e.g.
    "['id1', 'id2', 'id3']", and therefore the filter fails. This was
    already fixed for metadata filters, so just apply it to all filters.

    We do a try/except because if it really is a string, then the
    literal_eval will fail because we don't pass double quotes, such as
    "'string'". The current code therefore will now cover lists and
    fall back to the original behavior for strings.
