Add packer build for docker container

* Add docker Ubuntu Trusty packer template.
* Rework cmtools to install ansible and puppet
* Add support for Vagrant provider docker.
* Containers will share the host system docker daemon
  and images in the storage, so may be run nested.
* Ensure the rsyslogd and sshd is running in containers.
* Also ensure the /var/log/solar dir, which is required for docker.
* W/a Solar-hardcoded and vbox specific ssh key paths
  for docker case.
* Update FAQ and docs

Depends-on: I881d362968a10d816cbd368cb185900dfaa0b3bc
Partial-bug: #1547587

Note, vagrant does not support vm.network and exec based
provisioning for docker, so there are workarounds.

 You can also use multiple nodes `riak`, with some strong consistent buckets.
 
+.. _faq_solar_examples:
 
 Where can I find solar examples ?
 ---------------------------------
 
 Example resources, composer templates and examples itself are located:
 https://github.com/openstack/solar-resources
+
+.. _faq_solar_docker:
+
+Can I run solar nodes with docker ?
+-----------------------------------
+
+Yes, although that is an experimental feature and currently supports only
+a single network interface per a container. Note, that before to run the
+``vagrant up --provider docker`` command, the following preparations must be
+done at the host system:
+
+.. code-block:: bash
+
+  # docker pull solarproject/riak
+  # git clone https://github.com/kiasaki/docker-alpine-postgres.git
+  # cd docker-alpine-postgres
+  # make build && cd -
+
+This will allow the solar nodes to run required nested docker containers.
+
+.. note ::
+  The command ``vagrant ssh`` will not be working for the docker case.
+  Instead, use any of the following commands (with a correct name/IP):
+
+  .. code-block:: bash
+
+    # ssh vagrant@10.0.0.2
+    # docker exec -it solar-dev bash
