Gremlin wrapper for graph operations.
Parameters:
url (Optional[str]): The URL of the Gremlin database server or env GREMLIN_URI
username (Optional[str]): The collection-identifier like '/dbs/database/colls/graph'
or env GREMLIN_USERNAME if none provided
password (Optional[str]): The connection-key for database authentication
or env GREMLIN_PASSWORD if none provided
traversal_source (str): The traversal source to use for queries. Defaults to 'g'.
message_serializer (Optional[Any]): The message serializer to use for requests.
Defaults to serializer.GraphSONSerializersV2d0()
include_edge_properties (bool): Whether to include edge properties in
the gremlin graph schema. Defaults to False
Security note: Make sure that the database connection uses credentials
that are narrowly-scoped to only include necessary permissions.
Failure to do so may result in data corruption or loss, since the calling
code may attempt commands that would result in deletion, mutation
of data if appropriately prompted or reading sensitive data if such
data is present in the database.
The best way to guard against such negative outcomes is to (as appropriate)
limit the permissions granted to the credentials used with this tool.

Implementation details:
The Gremlin queries are designed to work with Azure CosmosDB limitations
