Pecan: filter values are not converted

[Salvatore Orlando]

The code [1], in order to work as expected, needs a call like [2].
Otherwise every filter value is sent down to the plugin as a string and the plugin will not like that.

    Pecan: filter items need type conversion

    In order for filtering to work properly on GET requests, filter
    values should be converted to the appropriate type specified in
    neutron.api.v2.attributes.RESOURCE_ATTRIBUTE_MAP.

    Without this change queries on boolean attributes, for instance,
    won't work as the value to filter on will be passed to the plugin
    as a string.

    Closes Bug: #1537924
