The cross-rack trunk (ch1, 4×1G) between core-sw01 and tor3-stor is
still static mode=on — no failure detection if a cable dies. Adding
command files to convert both switches to LACP during Friday's
maintenance window. Core hash stays layer-2-3 (5448 hardware limit);
stor hash stays layer-2-3-4 (already set).

Dell PowerConnect 5448 only supports layer-2, layer-2-3, and layer-3
load balancing (verified via console help output). The layer-2-3-4
option does not exist on this hardware. Current layer-2-3 setting is
already optimal. Removes the previously-prepped cmds file. [#369]

Dell PowerConnect 5448 currently uses layer-2-3 load balancing, which
caps any single-client datanet flow at one link (~1Gbps) even though
tsys5 has a 2-port LACP bond. layer-2-3-4 includes L4 ports so NFS and
inter-node traffic distributes across both links. Non-disruptive change.
Prepped for onsite console application. Related: [#369]

Add .cmds files for pulling MAC address tables and LLDP neighbor info
from core-sw01 and tor3-stor via conman console.
