[scenario] names of variables in scenario files are inconsistent

[Vitalii Gridnev]

There are several naming patterns of several variables in scenario files, for example:

[0] https://github.com/openstack/sahara-tests/blob/master/sahara_tests/scenario/defaults/vanilla-2.7.1.yaml.mako#L6
[1] https://github.com/openstack/sahara-tests/blob/master/sahara_tests/scenario/defaults/spark-1.3.1.yaml.mako#L6
[2] https://github.com/openstack/sahara-tests/blob/master/sahara_tests/scenario/defaults/mapr-5.2.0.mrv2.yaml.mako#L6

It would be more convenient if we will have the only pattern.
