Support users can query resources by specifying the time
that resources are created at or updated at with time
comparison operators: "gt/gte/eq/neq/lt/lte",
and cinder will return all which match the condition.
The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm.
The ±hh:mm value, if included, returns the time zone as an offset from UTC.
Add two filters updated_at and created_at in querying API.
"volumes/detail?created_at=gt:2016-01-01T01:00:00,lt:2016-12-31T01:00:00"
