[v2,6/6] usertools/setup: move removal target to 21.11

  There are still some functions in the script that not replaced
completely, give more time to complete removal of the tool.

A warning added to script documentation about the removal plan.

Current functionality supported by the script is:
 ----------------------------------------------------------
 Step 1: Setup linux environment
 ----------------------------------------------------------
 [1] Insert VFIO module
 [2] Display current Ethernet/Baseband/Crypto device settings
 [3] Bind Ethernet/Baseband/Crypto device to IGB UIO module
 [4] Bind Ethernet/Baseband/Crypto device to VFIO module
 [5] Setup VFIO permissions

 ----------------------------------------------------------
  Step 2: Uninstall and system cleanup
 ----------------------------------------------------------
 [6] Unbind devices from IGB UIO or VFIO driver
 [7] Remove IGB UIO module
 [8] Remove VFIO module
 [9] Remove KNI module

 [10] Exit Script
