JIRA: https://issues.apache.org/jira/browse/TINKERPOP-3095

Summary

Traversal-based remote requests can now choose the server script engine, as string queries already could via RequestOptions. This works in Java, Python, .NET, Go and JavaScript, in two ways:

• Per traversal source: g.with("language", "gremlin-lang")
• Per connection: a default for every traversal on a DriverRemoteConnection
  • Java: DriverRemoteConnection.using(cluster, "g", "gremlin-lang")
  • Python: language='gremlin-lang'
  • .NET: language: "gremlin-lang"
  • Go: settings.RequestLanguage
  • JavaScript: { language: 'gremlin-lang' }

A value set with with() overrides the connection default. If neither is set, nothing changes: .NET, Go and JavaScript still send gremlin-lang, and Java and Python let the server choose.

Bug fix: gremlin-go and gremlin-javascript silently dropped with("language", ...) from remote traversals because their option allow-lists omitted it. It is now sent.
