    Read template's expected value orchest test Part-1

    In tests under /tempest/api/orchestration/, resources gets
    created based on parameters defined in template (yaml, json).
    But while verification of output, expected values are hard coded
    in tests. Expected values should be read from template only.

    This patch adds the helper to load the values from template
    (yaml, json) and apply the changes in
    tempest/api/orchestration/test_volumes.py

    This patch also rename the existing load_template() function
    as it read the template and newly added function load the template
    This rename the load_template() to read_template in
    tempest/api/orchestration/base.py and corresponding calling files.
