Description of problem:
Smartstate analysis for AWS EC2 instance times out.

In my reproducer environment, I observed below log trace during the smartstate analysis:

~~~

And the smartstate analysis times out with below error:
~~~
ERROR -- : MIQ(VmScan#process_abort) job aborting, job timed out after 3059.463626564 seconds of inactivity.  Inactivity threshold [3000 seconds]
~~~

Version-Release number of selected component (if applicable):
CFME 5.9.4.7

How reproducible:
Always

Steps to Reproduce:
1. Add AWS provider
2. Configure SmartState Docker to perform SmartState Analysis on AWS
(I have put my Red Hat account credentials here)
3. Perform smartstate analysis on one of the AWS EC2 instance

Actual results:
Smartstate analysis fails

Expected results:
Smartstate analysis should succeed
