Description

We hard-coded the Ambari Agents to ignore certification
verification. But the reason why this was required was Python be un-secure by
default:
<https://access.redhat.com/articles/2039753>
<https://www.python.org/dev/peps/pep-0476/>

That method will cause signed certificates to not serve any purpose & is
discouraged by RedHat & Python security experts:

> "It is also possible, though highly discouraged , to globally disable
verification by monkeypatching the ssl module in versions of Python"

Instead we should abstract it to a setting (e.g. ssl_verify_cert) in the
ambari-agent.ini such that users can turn certification verification if they
provide a signed/trusted certificate.
