WIP: Created 2 introduction documents for user guide and installation

Work on the contant in both installation and user guide

Started to add artifacts in the installation instruction  and user guide

This is a first draft of the installation.introduction.rst and userguide.introduction.rst.
Some of the information has been reused from the Brahmaputra docs with  modifications.
Please comment and add as needed/wanted.

+Abstract
+========
+
+The following document provides an overview of the instructions required for the installation
+of the Colorado release of OPNFV.
+
+The Colorado release can be installed using a variety of technologies provided by the
+integration projects participating in OPNFV: Apex, Compass4Nfv, Fuel and JOID.
+Each installer provides the ability to install a common OPNFV platform as well as integrating
+additional features delivered through a variety of scenarios by the OPNFV community.
+
+============
+Introduction
+============
+
+The OPNFV platform is comprised of a variety of upstream components that may be deployed on your physical
+infrastructure.  A composition of components, tools and configurations is identified in OPNFV as a
+deployment scenario.
+The various OPNFV scenarios provide unique features and capabilities that you may want to leverage,
+it is important to understand your required target platform capabilities before installing and
+configuring your target scenario.
+
+An OPNFV installation requires either a physical, or virtual, infrastructure environment as defined
+in the `Pharos specification <http://artifacts.opnfv.org/pharos/colorado/docs/specification/index.html>`_.
+When configuring a physical infrastructure it is strongly advised to follow the Pharos configuration guidelines.
+
+=========
+Scenarios
+=========
+
+OPNFV scenarios are designed to host virtualised network functions (VNF’s) in a variety of deployment
+architectures and locations. Each scenario provides specific capabilities and/or components aimed to
+solve specific problems for the deployment of VNF’s.
+A scenario may, for instance, include components such as OpenStack, OpenDaylight, OVS, KVM etc...
+where each scenario will include different source components or configurations.
+
+To learn more about the scenarios supported in the Colorado release refer to the scenario
+description documents provided:

+======================
+Installation Procedure
+======================
+
+Detailed step by step instructions for working with an installation toolchain and installing
+the required scenario are provided by each installation project.  The four projects providing installation
+support for the OPNFV Colorado release are; Apex, Compass4nfv, Fuel and Joid.
+
+The instructions for each toolchain can be found in these links:
+
+- `Apex installation instruction <http://artifacts.opnfv.org/apex/colorado/docs/installationprocedure/index.html>`_
+- `Compass4nfv installation instruction <http://artifacts.opnfv.org/compass4nfv/colorado/docs/installationprocedure/index.html>`_
+- `Fuel installation instruction <http://artifacts.opnfv.org/fuel/colorado/docs/installationprocedure/index.html>`_
+- `Joid installation instruction <http://artifacts.opnfv.org/joid/colorado/docs/installationprocedure/index.html>`_
+
+=====================
+OPNFV Test Frameworks
+=====================
+
+If you have elected to install the OPNFV platform using the deployment toolchain provided by OPNFV
+your system will have been validated once the installation is completed.
+The basic deployment validation only addresses a small component of the capability provided in
+the platform and you may desire to execute more exhaustive tests.  Some investigation is required to
+select the right test suites to run on your platform from the available projects and suites.
+
+Many of the OPNFV test project provide user-guide documentation and installation instructions as provided below:
+
+- `Functest user guide <http://artifacts.opnfv.org/functest/colorado/docs/userguide/index.html>`_
+- `Yardstick user guide <http://artifacts.opnfv.org/yardstick/colorado/docs/userguide/index.html>`_
+- `vSwitchPerf user guide <http://artifacts.opnfv.org/vswitchperf/colorado/index.html>`_
+- `Software Fastpath Service Quality Metrics (SFQM) user guide <http://artifacts.opnfv.org/fastpathmetrics/colorado/index.html>`_
