Currently, when doing ceilometer-dbsync, ceilometer will create an
index for 'timestamp' field of meter collection. But the datatype
of the field is set to 'VARCHAR' which is not correct.
The patch insert a document with 'timestamp' before creating the
index of 'timestamp', then DB2 nosql will create the correct index
type for 'timestamp' field.
