Segment's MessageBuilder context is write-only which prevents additive context building #486

I am trying to add Segment integration for the Java SDK for FeatureHub (https://featurehub.io) - and I need to be able to capture the state of the features when a message is dropped to Segment. I want to augment the context, but if someone has another MessageTransformer which has set the context, I cannot add to that context (in the MessageBuilder), I can only overwrite it. I get we should create a new Map and stuff the existing data into it so we don't have cross SDK leakage, but we should be able to get the existing context.
