Be able to know when we are running inside a minor update workflow

With this change we add an ansible variable called
'tripleo_minor_update' set to true only during the update_steps_playbook
which get run during a minor update.
Then inside common/deploy-steps-tasks when starting containers with
paunch we export this 'tripleo_minor_update' ansible variable and
push it inside the 'TRIPLEO_MINOR_UPDATE' environment variable.

Inside change Id1d671506d3ec827bc311b47d9363952e1239ce3 we will then
use the env variable and export it to the restart_bundles in order
to detect if we're inside a minor update workflow (as opposed to
a redeploy - aka stack update). The testing that has been done is
described in the above change.

It is now possible for temporary containers inside THT to test if they are being run
as part of a minor update by checking if the TRIPLEO_MINOR_UPDATE environment
variable is set to 'true' (said containers need to export it to the container explicitely),
see <service>_restart_bundles for examples.
