Description of problem:
When running remediation playbook on 298 hosts, I see lots of warnings in the playbook output:

[WARNING]: Could not match supplied host pattern, ignoring: <some_hostname>

Version-Release number of selected component (if applicable):
satellite-6.7.0-7.el7sat.noarch

How reproducible:
always

Steps to Reproduce:
1. Schedule a remediation playbook on >100 hosts via FiFi. I'll attach mine playbook as it looks like FiFi/Receptor are not important to reproduce
2. Check output of individual host on Satellite: Monitor -> Jobs -> Ansible - run playbook... -> some host

Actual results:
There is lots of these warnings:

1:
[WARNING]: Could not match supplied host pattern, ignoring:
2:
gprfc016-01container20.contperf67.local
3:
[WARNING]: Could not match supplied host pattern, ignoring:
4:
gprfc016-01container208.contperf67.local
5:
[WARNING]: Could not match supplied host pattern, ignoring:
6:
gprfc016-01container209.contperf67.local
[...]

Expected results:
No warnings

Additional info:
Adam Ruzicka explained me reason for these: Foreman obtains a playbook for all the hosts at once. These hosts are all namely listed in "hosts:" directive of the playbook. Then Foreman starts the same playbook multiple times for subsets of 100 hosts - that makes ansible to report 298 - 100 hosts are missing in the inventory and print the warning.
