Mitsuhiro Tanino 70c6a35684 Graceful shutdown WSGI/RPC server 
Currently, termination of WSGI application or RPC server immediately stops
service and so interrupts in-progress request.

Graceful handler for SIGTERM signal was added.
SIGINT signal handler was removed to allow instantaneous termination of
service.

DocImpact: graceful termination of process can be done by sending SIGTERM
signal to parent WSGI process. Graceful termination is not instantaneous.
To force instantaneous termination SIGINT signal must be sent.

(cherry picked from commit 13ce823686062d70b268b4d3888849adef07e4ff)
  Additional fix: oslo.service provides this facility through it's wait()
                  method, so we need to call it in Cinder Service wait()
                  method which gets called when graceful shutdown is
                  requested by sending the process SIGTERM.

README 

openstack-common
----------------

A number of modules from openstack-common are imported into this project.

These modules are "incubating" in openstack-common and are kept in sync
with the help of openstack-common's update.py script. See:

  https://wiki.openstack.org/wiki/Oslo#Syncing_Code_from_Incubator

The copy of the code should never be directly modified here. Please
always update openstack-common first and then run the script to copy
the changes across.
