Bug Description

On devstack multi nodes env, I have 1 controller and 2 computes.

I launched 1 instances: theses lasts are deployed on both compute nodes.
I created an audit with BASIC_CONSOLIDATION goal. the expected action plan is correct : It proposed to migrate one instance to
other compute node, and "shutdown" the empty compute node.

When I started the proposed action plan, instance migration has failed due to migration 'block_migrate' option set to True.
on devstack multi nodes env, we use shared FS for instance files, so this option is incompatible.

    Use taskflow library for building and executing action plans

    The aim of this patchset is to integrate taskflow in
    the Watcher Applier. Taskflow will help us a lot to make
    Action Plan execution easy, consistent, scalable and reliable.


    Partially implements: blueprint use-taskflow
