Support IPROTO_AFTER_TUPLE in Select request

[Vlad-Zaytsev]

In case when you want to download a huge collection in batches (whole space, for example) switch from IPROTO_OFFSET to IPROTO_AFTER_TUPLE would make a big difference.

The problem is that it was added in 2.11. So test environment should include taranool 2.11 (or maybe 3.0, or even later).
And I think client should take into account actual server version and raise an exception in case of passing AfterTuple to older server.

Seems not a very complicated feature and I can try to make PR myself. Just hope this repo is still maintained.

@Vlad-Zaytsev kinda maintained. If you're willing to do several rounds of review, let's do it.

No SLA on response time, though.

What you think about supported versions? Maybe we should abandon older versions and target 3.0?

We should definitely support 2.11 as it still used very actively.

We can definitely drop 1.* support.
