bmcsetup: enhance BMC port configuration for Dell systems

Browse Source 
Add optional values to ipmi.bmcport to support more fine-grained
configuration for Dell servers, and mirror the `ipmitool delloem`
capabilities:

   lan set <Mode>
    sets the NIC Selection Mode :
        dedicated, shared with lom<idx>

   lan set <Shared Failover Mode>
    sets the shared Failover Mode :
        shared with failover lom<idx>
        shared with failover all loms,
        shared with failover none.

This patch introduces the possibility to provide 3 (space-separated)
values for ipmi.bmcport:
  1st value:  0 = shared / 1 = dedicated
  2nd value   shared LOM (1-4)   (0 or no value means first available LOM)
  3rd value:  failover LOM (1-4) (0 means no failover, no value means all LOMs)

To ensure maximum compatibility with the default 0/1 shared/dedicated
scheme, the 2nd and 3rd values are optional, and will retain the
previous behavior when not specified.

Examples:

ipmi.bmcport value      BMC interface configuration
0                       Shared with first available interface, failover with
                        all LOMs (catch-all mode)
0 1                     Shared with LOM1, failover all LOMs
0 1 2                   Shared with LOM1, failover LOM2
0 2 0                   Shared with LOM2, no failover
1                       Dedicated
