[Memoization 9/n] Add version_strategy as an arg to pipeline definition.

Description

[Memoization 9/n] Add version_strategy as an arg to pipeline definition.

Summary: Considering we're keeping backcompat alive for a long time, and this is super low-cost, makes sense to support it.

Test Plan: added test with using version_strategy on pipeline decorator.
