Eventlet, when monkey patching occurs, replaces the base
dns resolver methods. This can lead to compatability issues,
and un-expected exceptions being raised during the process
of monkey patching. Such as one if there are no resolvers.
As such, since we don't really need monkey patching of DNS,
and setting the flag should make the inspector CI jobs happier
where we don't need nor use DNS, AND tinycore may not be setting
a resolver configuration at all, which is the root of the failure
upon monkey patching that casues IPA to fail on start in certian
circumstances.
As a note, this has been performed on other projects due to
bugs. See Id9fe265d67f6e9ea5090bebcacae4a7a9150c5c2.
