1、As mentioned in [1], we should avoid using six.iteritems/keys
   achieve iterators. We can use dict.items/keys instead, as it
   will return iterators in PY3 as well. And dict.items/keys will
   more readable.
2、In py2, the performance about list should be negligible,
   see the link [2].

As we known, Exceptions are raised by the sys.exit() function. When they
are not handled, no stack traceback is printed in the Python interpreter.

In this patch we have known main() got return values(eg:0, 1), but
it can't specifies exit status when terminate the main thread by
unusing sys.exit(). So when using sys.exit(main()) instead of main()
may be more readable and reasonable.

Watcher is part of the OpenStack big-tent and is formally
known as "OpenStack Infrastructure Optimization service".

Whilst it provides a range of default goals and strategies,
the most relevant case is to enable re-balancing of the
compute hosts by taking CPU usage (data from Ceilometer)
into account and live migrating instances as required.

Currently this only builds the Docker images for type source
but binary builds are gracefully ignored.

The ansible configurations will be part of a later commit.

Instead of having the program sys.exit when a docker
client object can not be created (which kills all the threads
and messes up the program and its associated state) have a
exception be raised when this (for whatever reason) fails.

Also refactor so that there is a docker task that the docker
client using tasks can all inherit from.

Instead of using the same logger for all the things
which makes it incredibly hard to figure out what the images
and there builds are doing; instead have it so that each
image gets its own logger which is then used by tasks that
process that image.

Each images logs now will (optionally) go to a logs directory
that can be more easily read and looked over and leaves
the main logger for informational/task kind of
output only.

This patchset enables potentially full customization of Dockerfiles
provided by Kolla without having to change main Kolla code. Mechanism is
based on jinja2 block mechanism. In our dockerfiles we'll add blocks
(mostly empty) with highly standarized naming, then in override file
users will be able to fill/override contents of these blocks. Example is
shown in this patch.
To enable cutomized override file call build.py

--template-override=path-to-file Only caveat is that header {% extends
.. %} has to stay

Instead of using raw dicts and passing data around via
dictionaries (which makes it really hard to figure out
what is in those dictionaries at any point) prefer to
use objects. That way people can actually understand what
the object is supposed to be, vs guessing and/or having to
decipher its usage.

The same goes for raw string constants, prefer using
named constants instead.

Instead of having smart workers that need to know
about the full logic of how they operate and what
they will do which makes it hard to reuse parts of
those workers switch the model so that workers are
dumb and they just run tasks which themselves can
request additional tasks to run when succesful.

This makes it more consistent when tasks are to
be retried and also makes it easier to know which
task is running and when.

Less specialized workers == good.

Only Lbaasv2 is supported in Mitaka. Additional information can

Magnum uses Neutron Lbaas to provide high availability to COE API
and Etcd endpoints within a bay. Therefore, Neutron Lbaas is required
