Ensure CentOS package updates are consumed by SWARM tests

[Vitaly Sedelnik]

As we started to ship package updates for CentOS via repositories on http://pkg-updates.fuel-infra.org/ we need to consume those package during testing.

Links to package updates repos for all affected versions:
- 6.1 and 7.0: http://pkg-updates.fuel-infra.org/centos6/
- 8.0: http://pkg-updates.fuel-infra.org/centos7/
