Allow customized strategy in case labels (or relationship types) have same name but different cases

[santo-it]

With current version, 2.2.14:

• Neo4j Nodes with same Label but different case, e.g. LABEL and LAbel will be aggregated into a single OrientDB vertex Class
• Neo4j Relationship with same name but different case, e.g. relaTIONship and RELATIONSHIP will be aggregated into a single OrientDB edge Class

This is an enhancement request to allow users to customize the strategy. The above can be one strategy, but other strategies are possible, e.g. append a random string to the label or relationship type, and migrate them into separated classes

This seems to be not a common case - but could be useful to improve how we behave here anyway
