"MIGRATE" action triggered by Watcher Applier failed on devstack

[David TARDIVEL]

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.

Waiting for implementation of https://blueprints.launchpad.net/watcher/+spec/watcher-add-actions-via-conf before to propose a fix

    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.
