Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1465787

Description of problem:
Having local ssh configuration for ProxyCommand that contains "nc" like:

1. cat /usr/share/foreman-proxy/.ssh/config
   Host proxyserver
   ProxyCommand

Host *
ProxyCommand ssh -q -i /usr/share/foreman-proxy/.ssh/id_rsa_foreman_proxy proxyrex@proxyserver nc %h %p #

then invoking and REX job leaves one ssh zombie proces.

smart_proxy_dynflow_core service must be restarted to clean the ssh defunct processes

Version-Release number of selected component (if applicable):
Sat 6.2.9

How reproducible:
100%

Steps to Reproduce:
1. Have above-like ssh config
2. Run a REX job - it can fail or succeed, it doesnt matter. Even it can fail due to wrongly set .ssh/config, that does not matter either.
3. Check ssh processes on the Satellite/Capsule that invoked the ssh commands

Actual results:

1. ps aux | grep defunct
   foreman+ 24776 0.0 0.0 0 0 ? Z 13:06 0:00 [ssh] <defunct>
   foreman+ 24848 0.0 0.0 0 0 ? Z 13:07 0:00 [ssh] <defunct>
   root 24856 0.0 0.0 112652 964 pts/0 S+ 13:07 0:00 grep --color=auto defunct #

(each REX job adds one such defunct process)

Expected results:

1. ps aux | grep defunct
   root 24856 0.0 0.0 112652 964 pts/0 S+ 13:07 0:00 grep --color=auto defunct #
