Description

Currently primitive map type in atlas is stored in vertex as:

• typeName.mapAttr         = [key1, key2, key3]
• typeName.mapAttr.key1 = value1
• typeName.mapAttr.key2 = value2
• typeName.mapAttr.key3 = value3

Since JanusGraph supports Map datatype, we can store map value within a single vertex property.

Also we need to create edge label and property key for array and map primitive types.
