Refactor userguide "Yardstick Installation"

[1] must be refactored in order to:
  * Include proxy options.
  * Use OpenStack client, instead of project CLI.
  * Use sudo in some commands.
  * Adapt the document to rst coding style.
  * Fix minor errors.

-Proxy Support (**Todo**)
----------------------------
+Proxy Support
+-------------
+
+To configure the Jumphost to access Internet through a proxy its necessary to
+export several variables to the environment, contained in the following
+script::
+
+   #!/bin/sh
+   _proxy=<proxy_address>
+   _proxyport=<proxy_port>
+   _ip=$(hostname -I | awk '{print $1}')
+
+   export ftp_proxy=http://$_proxy:$_proxyport
+   export FTP_PROXY=http://$_proxy:$_proxyport
+   export http_proxy=http://$_proxy:$_proxyport
+   export HTTP_PROXY=http://$_proxy:$_proxyport
+   export https_proxy=http://$_proxy:$_proxyport
+   export HTTPS_PROXY=http://$_proxy:$_proxyport
+   export no_proxy=127.0.0.1,localhost,$_ip,$(hostname),<.localdomain>
+   export NO_PROXY=127.0.0.1,localhost,$_ip,$(hostname),<.localdomain>
+
+To enable Internet access from a container using ``docker``, depends on the OS
+version. On Ubuntu 14.04 LTS, which uses SysVinit, ``/etc/default/docker`` must
+be modified::
+
+   .......
+   # If you need Docker to use an HTTP proxy, it can also be specified here.
+   export http_proxy="http://<proxy_address>:<proxy_port>/"
+   export https_proxy="https://<proxy_address>:<proxy_port>/"
+
+Then its necessary to restart the ``docker`` service::
+
+   sudo -EH service docker restart
+
+In Ubuntu 16.04 LTS, which uses Systemd, its necessary to create a drop-in
+directory::
+
+   sudo mkdir /etc/systemd/system/docker.service.d
+
+Then, the proxy configuration will be stored in the following file::
 
+   # cat /etc/systemd/system/docker.service.d/http-proxy.conf
+   [Service]
+   Environment="HTTP_PROXY=https://<proxy_address>:<proxy_port>/"
+   Environment="HTTPS_PROXY=https://<proxy_address>:<proxy_port>/"
+   Environment="NO_PROXY=localhost,127.0.0.1,<localaddress>,<.localdomain>"
+
+The changes need to be flushed and the ``docker`` service restarted::
+
+   sudo systemctl daemon-reload
+   sudo systemctl restart docker
+
+Any container is already created won't contain these modifications. If needed,
+stop and delete the container::
+
+   sudo docker stop yardstick
+   sudo docker rm yardstick
+
+.. warning:: Be careful, the above ``rm`` command will delete the container
+completely. Everything on this container will be lost.
+
+Then follow the previous instructions `Prepare the Yardstick container`_ to
+rebuild the Yardstick container.
