Remove default_params_with_timeout_values variable

default_params_with_timeout_values was only supposed to
used under baremetal tests but it was kept because many plugins
were using the same.
Now all plugins have been fixed for this.
Last fix is merged - I8d010afe20db890636433a17193029a123a0a136

This commit removes default_params_with_timeout_values from tempest.
