6wind-virtual-accelerator-plugin: fix to support 9.1

Starting from 9.1 release, a new way to execute plugin tasks
has been defined by Fuel.
This new mechanism breaks 6WIND plugin even on recent system
using 9.0 because modifications have been made on MOS distant
repos (used for both 9.0 and 9.1).

This fix moves the execution of plugin tasks in the post deployment
stage to avoid the failures.
