A simple struct containing a full position, including a partition key and a position in partition. Two variants are introduced: an owning version and a view. This is to replace all the ad-hoc structures introduced for the same purpose: std::pair() and std::tuple() of partition key and clustering key, and other similar small structs scattered around the code. This patch does not replace any of the above mentioned construcs with the new full_position, it merely introduces it to enable incremental standardization.
