comment Jenkins server built permissions
typically /usr/local/lib/python2.7/dist-packages is owned by root user. Unless there is any reason why you don't want to install these packages in there, I'd use root to install the stuff, which is not to say that you should run the stuff as root, I'd use the jenkins system account for that.

comment how to run nohup when prompted for password and/or input parameter
I think check if autoexpect program is available to you, then you can run autoexpect and the interactive script you wanted to run. That will generate the expect script needed.

comment Foreman DNS Error ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry
If having problems with the foreman-proxy, then looking in the foreman-proxy log is an excellent first step, it has helped mi solve 100% of all problems associated with it. If setting log level to DEBUG, you'll be able to see excactly what is going on.
