If this could be solved in a more optimized way for the http provider, please show me how.

I've left this in - but the test for the new operations seem to suggest this path will never be hit (since result is either null or a value, not DBNull.Value). Similar remark in other relational store implementations.

This PR introduces two new methods on
IReadonlyStreamStore(non-breaking change):ReadStreamHeadPosition: reads the head position of a stream, i.e. the position of its last messageReadStreamHeadVersion: reads the head version of a stream, i.e. the version of its last messageThe test suite was extended with additional acceptance tests to cover the behavior of these new operations. This is the basis for a follow-up PR (in that it will follow a similar pattern) which will introduce support for reading the stream head message as well as the all stream head message.
