Migrate delete_array and delete_fragments from StorageManager to Array.

[bekadavis9]

Migrate Array APIs out of StorageManager: delete_array and delete_fragments. Note: this migration required addition of new, static versions of these internal APIs on class Array, which effectively do exactly what the versions in StorageManager were previously doing. This allows for a "hierarchical-like" structure among the inter-dependent APIs delete_group, delete_array, and delete_fragments.

FYI, the REST-CI failure should go away if you rebase to latest dev , it's due to sc-44928
