This patch removes the support of tox-ansible from
tripleo-validations. Due to several issues with pip dependencies
management and our requirements files, the installation of this latter
doesn't work.
This patch also removes the `tripleo-linters` anchor and nodeset line
for the `openstack-tox-linters` check job as they are not used or useful
here.
