new pull consumer and ephemeral consumer options

[aricart]

Overview

The following consumer options can now be set on a consumer (applying only to pull consumers):

• max_batch (number)
• max_expires (number - duration - nanos)

For ephemeral consumers, the following option can now be set:

• inactive_threshold (number - duration - nanos)

Currently, these options can be set on any consumer, an issue has been filed on the server to reject them if not set on the correct consumer type. This would alleviate validation on the client-side. These properties on 2.7.1 can also be updated.
