Add an attempt to remove armada using force parameter

Sometimes the attempt to remove the armada pods
get stuck due another starlingx resources. This
commit added to the armada script an attempt to
remove the pods when the previous attempts fails.

Test Plan:
PASS: AIO-DX stx-8 install
PASS: upgrade stx-8 to master and observe if script
      01 was executed with success during activate
      process.
PASS: Edit script 01 making the normal attempts to
      remove the pod fails and check if the script
      successfully force the pod remove.
