Session token and transactional batch

[mwikstrom]

Is your feature request related to a problem? Please describe.
I want to keep session consistency up to date when using transactional batch.

Describe the solution you'd like
I'd like the transactional batch operation to accept a session token (perhaps via an options construct similar to other operations) and then return an updated session token in its response.

Describe alternatives you've considered
If one really need to ensure that session consistency is up to date after executing a transactional batch operation the only option I've come up with is to:

1. Execute the batch
2. Capture one of the new item's ETag and Timestamp
3. Query container with current session token repeatedly until the new ETag is visible or a greater Timestamp is observed

In most cases this will incur a single extra round trip but could potentially require many extra round trips.
