Remove havana compat from nova.console.rpcapi

Since we only support upgrading from N-1 to N, there's no
need to keep around this older upgrade related code.

libvirt: pin emulator threads to union of vCPU cpuset

Ensure that the emulator threads run on the same host CPUs as
the vCPU threads do, by setting the emulator pinning to be the
union of vCPU pin cpuset

Use session in cinderclient

Use the common session loading parameters and the session object for
talking to cinder.

There are some related changes in this patch.

Firstly auth_token middleware now provides an authentication plugin that
can be used along with the session object to make requests under the
user's authentication. This will largely replace the information
required on the context object.

This authentication plugin is not serializable though and so it cannot
be transferred over RPC so we introduce a simple authentication plugin
that reconstructs the required information from the context.

When talking to cinder we now create a global session object (think of
this like keeping open a connection pool object) and use the
authentication plugin to send requests to cinder.

I also condense the cinder tests as they are largely copied and pasted
between v1 and v2 and this solves fixing them in two places.

DocImpact: Renames cinder's timeout, insecure and CA certificates
parameters to the parameters used by the common session object. Adds
options for using client certificates with connection.

Replacement `_` on `_LI` in all LOG.info - part 1

oslo.i18n uses different marker functions to separate the
translatable messages into different catalogs, which the translation
teams can prioritize translating. For details, please refer to:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html#guidelines-for-use-in-openstack

There were not marker fuctions some places in directory network.
This commit makes changes:
* Add missing marker functions
* Use ',' instead of '%' while adding variables to log messages

Added a hacking rule for the log info about checking
translation for it.
