Cisco UCS server support in baremetal variants

[etungsten]

What I'd like:
Bottlerocket baremetal variants to support Cisco UCS servers by having the necessary drivers to boot properly.

Specifically, we should be looking at enabling:
CONFIG_NET_VENDOR_CISCO
Cisco VIC Ethernet NIC Support

Checked current config status and that those two are the only Cisco networking settings that are interesting (in fact these two seem to be the only cisco specific options for wired networking).

Will add them to the metal specific config once we have merged the PR for that (#2264)

Looking at this some more there might be additional things we might need on the storage front for these boxes.

There is what Cisco calls fNIC which they use for virtual HBA via Fibre channel over ethernet (as far as I understand):

FCOE_FNIC
-> (depends on LIBFCOE which we have as Module)
-> (depends on LIBFC which we have as Module)

Then there is what Cisco calls sNIC which is their SCSI HBA driver:

SCSI_SNIC

Finally, there is infiniband support for Cisco VIC:

INFINIBAND_USNIC

With merge of #2271 this is done.
