move graph connector creation to new op (#2923)

Moves the generation of graphConnector to the
NewBackupOp and NewRestoreOp constructors
inside the repository.  This removes gc creation
from the backup and restore operations, and
requires a reference to gc to exist in operations.

This sets up two changes: 1/ mocking of GC
within operation (the next PR will replace it with
an interface).  2/ the ability to perform a gc
validation step within the operation construction,
and thus the capacity to look up a resource owner
display name or id, and vice versa.
