Description of problem:
1. Support for option SysVStartPriority= has been removed and it is ignored
2. supervisord.service does not have dependency on remote user resolution, but is required in many enterprise environments.

Version-Release number of selected component (if applicable):
supervisor-3.1.3-3.el7

How reproducible:
very

Steps to Reproduce:
1. Install RHEL 7.3 w/ supervisor from EPEL
2. systemctl deamon-reload will trigger the warning
3. The remote user resolution dependency would require LDAP and is timing.

But based on the updated & tested cgred.service in RHEL 7.4 Bug 1406927 the following supervisord.service should work

Changes:
1. Remove 'SysVStartPriority=99' as systems log states this has been removed
2. Add nss-user-lookup.target to After= line so remote user can be resolved at start
~~~
[Unit]
Description=Process Monitoring and Control Daemon
After=rc-local.service nss-user-lookup.target

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf

[Install]
WantedBy=multi-user.target
~~~



Actual results:
1. log: Support for option SysVStartPriority= has been removed and it is ignored
2. Race condition with remote user lookup


Expected results:
1. No warning to syslog 
2. service file configured to start after remote user lookup (no race)


Additional info:

For above to fully work with NIS, need the following private BZ addressed in RHEL 7.4 beta currently

 Bug 1217435 - ypbind.service should be loaded before nss-user-lookup.target
