Id518a6d87d0949737cd1c50cb6a83149b85e5f85 removes the
class variable from tempest - 'default_params_with_timeout_values'
This was kept in tempest only to be used for baremetal tests.
Each Temepst plugin should either have their own config options
for build timeout etc or use the default one.
Currently this commit makes use of timeout and other values from
config which are stable.
