mgmt: LpFace faces/enable-local-control workaround
In this temporary workaround,
faces/enable-local-control enables all local fields in GenericLinkService,
and faces/disable-local-control disables all local fields in GenericLinkService.
This commit also modifies FaceTable::remove to retain shared_ptr<Face>
until signal execution is complete.
