Description of problem:
foreman_scap_client command fails with execution expired (Timeout::Error)

Version-Release number of selected component (if applicable):
Satellite 6.4.2

How reproducible:
N/A

Steps to Reproduce:
Not able to reproduce. However, configuring a read_timeout in the scap client get rid of the timeout errors.

NOTE: Even though the client errors out, OpenSCAP reports are uploading just fine.

Actual results:
Running a foreman_scap_client fails with the following error

Expected results:
Make read_timeout configurable under /etc/foreman_scap_client/config.yaml file

Additional info:

NOTE: Even though foreman_scap_client command errors out, client openscap reports uploads without any issues. 

Increasing proxy_request_timeout and applying a patch from https://projects.theforeman.org/issues/25501 didn't help. 

Issue was fixed by adding a read_timeout in client configuration as below

 On RHEL 6 : /usr/lib/ruby/gems/1.8/gems/foreman_scap_client-0.3.0/lib/foreman_scap_client/client.rb
 On RHEL 7 :  /usr/share/gems/gems/foreman_scap_client-0.3.0/lib/foreman_scap_client/client.rb
