    Fixes dict metadata query issue of HBase

    Now HBase doesn't support query the metadata with the dictionary
    type. For example, the metadata of Glance image always has the
    metadata "properties" which is dictionary and has some attributes,
    size, kernel id, etc. So this fix will enable the HBase driver of
    CM to support query like "metadata.properties.tag=test".

    Fixes bug 1206022
