Grzegorz Grasza 9bc06783ec Add RPC and object version pinning 
To support rolling upgrades, capping of RPC communication and Ironic
objects is required. Old RPC services and objects may still be running
while an upgrade is in progress. This makes sure that these old
services are called and all objects are used in a supported RPC and
objects version.

This patch adds the configuration option "pin_release_version". Setting
this option caps (downgrades) the internal RPC communication to the
specified version to enable communication with older services. When
doing a rolling upgrade from version X to Y, set this to X. It defaults
to using the newest (current) possible RPC behavior and object versions.

Ironic

Ironic consists of an API and plug-ins for managing and provisioning physical machines in a security-aware and fault-tolerant manner. It can be used with nova as a hypervisor driver, or standalone service using bifrost. By default, it will use PXE and IPMI to interact with bare metal machines. Ironic also supports vendor-specific plug-ins which may implement additional functionality.

Ironic is distributed under the terms of the Apache License, Version 2.0. The full terms and conditions of this license are detailed in the LICENSE file.
