[8.0][acceptance] Test for Remove two controllers fails on check /etc/hosts files

[Vadim Rovachev]

Test https://github.com/openstack/fuel-qa/blob/stable/8.0/fuelweb_test/tests/tests_scale/test_scale_group_2.py#L108
contains check for hosts in /etc/hosts file after remove nodes, but after discussion with our developers we decided, that /etc/hosts don't change on remained nodes after delete some other.
Need to change test according to latest news.
