Updating Janusgraph existing index constraint

[shubhamparikh927]

I have created a composite index with unique constraint into janusgraph. After that I have loaded millions of records, butdue to some technical problems I have to remove the unique constraint of the index. Is it possible ?

byCodeIndex = mgmt.buildIndex(PropertyConfig.INDEX_CODE_VERTEX_CODE, Vertex.class).addKey(propertyKeyCode).unique().buildCompositeIndex();

I dont want to create new index, just want to update the index by removing its unique constraints.
