Add ucsrancid for Cisco UCS devices

This is a really quick'n'dirty adaptation of the original rancid script
meant for Cisco UCS devices. It dumps the output of the following
command with minimal post-processing:

  show version
  show chassis inventory expand detail
  show fabric-interconnect inventory expand detail
  show configuration
Set $TERM to "linux" in zrancid

The previous value (vt100) caused some terminal control characters to be
printed, which confused the prompt detection and caused spurious diffs.

Revert "Set $TERM to "linux" in zrancid"

This reverts commit 31cd599658816cd8a17b75ed0ded74337e628878.

This was committed to the wrong branch unfortunately.
