Removes vim configuration headers

 - Removes vim headers: It's not needed to set tabstop tons of times,
   this can be done by setting vimrc.
 - I did not update files in common/* and install_venv_common.py because
   these files are sync with oslo.

Using floating-ip-{associate|disassociate}

This patch implements a blueprint to add more consistency into
nova command, especially for the subcommand "floating-ip-*"

Currently when we want to associate or disassociate an ip with
nova we have to use add-floating-ip and remove-floating-ip. This
is not consitent with the actual scheme of the subcommands:

example:
  nova image-*
  nova flavor-*
  nova floating-ip-*

 + In the client v1.1 this patch displays a deprecated message when printing
   the help message for add-floating-ip and remove-floating-ip.
 + In the client v3 this patch do nothing because all floating ip commands are being
   removed.
