The volume of logs we collect in CI jobs are extensive. This
patch ensures that the logs collected are compressed to reduce
the space taken in CI systems.
PYTHONUNBUFFERED is also set to ensure that the console log
from the CI jobs is recorded in the exact order of execution.

Some Linux distributions, such as CentOS 7 and Xenial, have trouble
validating SSL certificates when using get_url with servers
that use Server Name Indication (SNI).
This patch adds those packages to the list of required packages and
uses bindep to install them in developer test environments the same
way that the gate tests install them.
