Devops guide update

[Stanislav Makar]

Remove the section "Devops Installation from packages" due to this does not work correctly
I want to propose to leave the "Devops installation in virtualenv" and full fill it with all necessary information
from "Devops Installation from package".

When run:
./utils/jenkins/system_tests.sh -t test -w $(pwd) -j fuelweb_test -i $ISO_PATH -V /home/ubuntu/devops-venv2 -o --group=setup

I get:
...
raise AppRegistryNotReady("Models aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.

This error is coused by django 1.7
When downgrade to 1.6.7 - all is working( pip install django==1.6.7 )

Stanislav, I'd prefer you do not remove whole sections from the docs "Devops Installation from packages". It's rather to specify how make it works.

If it doesn't works corrently because of missed packages please add devops external repository to the doc: http://mirror.fuel-infra.org/devops/ubuntu

Thanks!

 Igor , It would be cool but there are some problems:
-- the script utils/jenkins/system_tests.sh has the hardcoded strings (https://bugs.launchpad.net/fuel/+bug/1377183/comments/1)

        if [ -z "${VENV_PATH}" ]; then
            VENV_PATH="/home/jenkins/venv-nailgun-tests"
        fi

      And if we change it, it can brake the CI system. CI system has to be reconfgured

-- if we install the package python-devops from package ( http://mirror.fuel-infra.org/devops/ubuntu repo)
      and then install the fuelweb_test requirements
             git clone https://github.com/stackforge/fuel-main
             cd fuel-main/
             sudo pip install -r ./fuelweb_test/requirements.txt --upgrade

      here pip reinstalls the devops from git, the because fuelweb_test/requirements.txt has the string:
      git+git://github.com/stackforge/fuel-devops.git@2.4.3

     here is question: does worth to install it from package(connect repo) if it is reinstalled from git ?

[Igor Shishkin (teran)]

Stanislav, installing from git is a legacy. Basically we should install from git fuel-main only, all dependencies should come from packages. So while we're in middle of moving to packages we're supporting both ways.
