Merge "phage" from "experimental"

Summary: Ref T13395. Currently, "phage" is required for various cluster operations. Bring the working code out of "experimental". This isn't the final form; "wilds" has a fancier version.

Test Plan: Ran phage workflows against the cluster.

Maniphest Tasks: T13395
