[Bug 1518016] [NEW] Nova kilo requires concurrency 1.8.2 or better

[Mohammed Naser]

Public bug reported:

OpenStack Nova Kilo release requires 1.8.2 or higher, this is due to the
addition of on_execute and on_completion to the execute(..) function.
The latest Ubuntu OpenStack Kilo packages currently have code that
depend on this new updated release.  This results in a crash in some
operations like resizes or migrations.

This commit above shows that OpenStack now requires 1.8.2 instead of
1.8.0.  We would appreciate if the 1.8.2 upstream release can be brought
in to resolve this bug.

Thank you.
