Subject: [PATCH] net/sysconfig: enable sysconfig renderer if network manager
has ifcfg-rh plugin (#4132)
Some distributions like RHEL does not have ifup and ifdown
scripts that traditionally handled ifcfg-eth* files. Instead RHEL
uses network manager with ifcfg-rh plugin to handle ifcfg
scripts. Therefore, the sysconfig should check for the
existence of ifcfg-rh plugin in addition to checking for the
existence of ifup and ifdown scripts in order to determine if it
can handle ifcfg files. If either the plugin or ifup/ifdown scripts
are present, sysconfig renderer can be enabled.
fixes: #4131
RHBZ: 2194050

(cherry picked from commit 009dbf85a72a9077b2267d377b2ff46639fb3def)
