Review Comment:
This is implemented as dynamic auth so that the returned value can't be
changed after use, e.g. by setting the public fields of the AuthInfo struct.

> Components: go
> Reporter: Lyndon Bauto
> Priority: Major

> Gremlin Go currently supports custom authentication headers.
>
> For long running connections that reconnect over time, these headers can
> expire.
>
> We should allow injection of a function pointer to generate the header.
