John Kung bd998017d5 SysInv Decoupling: Create Inventory Service
Create host inventory services (api, conductor and agent) and
python-inventoryclient.

The inventory service collects the host resources and provides a
REST API and client to expose the host resources.

Create plugin for integration with system configuration (sysinv)
service.

This is the initial inventory service infratructure commit.
Puppet configuration, SM integration and host integration with
sysinv(systemconfig) changes are pending and planned to be
delivered in future commits.

Tests Performed:
 Verify the changes are inert on config_controller installation
 and provisioning.
     Puppet and spec changes are required in order to create keystone,
     database and activate inventory services.

 Unit tests performed (when puppet configuration for keystone, database
 is applied):
     Trigger host configure_check, configure signals into
         systemconfig(sysinv).

     Verify python-inventoryclient and api service:
         Disks and related storage resources are pending.
         inventory host-cpu-list/show
         inventory host-device-list/show/modify
         inventory host-ethernetport-list/show
         inventory host-lldp-neighbor-list
         inventory host-lldp-agent-list/show
         inventory host-memory-list/show
         inventory host-node-list/show
         inventory host-port-list/show

     Tox Unit tests:
         inventory: pep8
         python-inventoryclient: py27, pep8, cover, pylint
