ETag not available through SDK

[ibrechin]

I've been looking at using the REST API functionality to avoid update conflicts (https://www.twilio.com/docs/usage/mutation-and-conflict-resolution) but although the if_match param is supported by the python SDK, I can't see any way of accessing the ETag header from SDK objects, in the docs or the source code. Version.fetch only parses the response.text, as does Page.process_response.

Am I missing something or is this absent? If the latter, could some way of accessing the Etag be added?

As of now, the SDK does not provide access to ETag header. This can be a feature request for the SDK which we can prioritize based on the +1s that we get over here or if there is a PR for this change, we can review it. Thanks!
