So UpdateDelegation, DeleteDelegation, AddTargets, RemoveTargets now
all check for the role existence, not metadata existence. And they
also check the role's signing keys - there's no point in adding if
we can't sign.

Previously we were always signing it, but we can't do that anymore
because then delegated users won't be able to publish ever (they
probably don't have the target key).
Some other related changes: when role keys are rotated, that role
needs to be marked as dirty now in order to be re-signed and
published.

Only create it when a target is added to it, or other delegations
are added to it, or when getting a child delegation.
