toolbox: Allow different users logging to ansible.log

Currently only operations done with default kolla_toolbox user are logged
to /var/log/kolla/ansible.log.

In order to fix logging, permissions to ansible.log must allow writing
for other users in kolla group - and then a separate patch will follow
to make custom ansible.cfg file usable by other toolbox users.
