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.
