Add options for failing resource check on command line

[cthorn42]

When running puppet resource service, and the service does not exist, the application will return a 0 exit code and display that the service is not running.
This PR introduces a new option for the puppet resource service application, --fail, if the service is not found and the option is used, the application will return with a non-zero exit code, and display an error message.
Example of use:

[root@potent-image ~]# puppet resource service made_up_service ensure=running --fail
Error: Systemd start for made_up_service failed!
journalctl log for made_up_service:
-- No entries --

Error: /Service[made_up_service]/ensure: change from 'absent' to 'running' failed: Systemd start for made_up_service failed!
journalctl log for made_up_service:
-- No entries --

Error: Could not run: Failed to manage resource Service[made_up_service]
[root@potent-image ~]# echo $?
1

Here is an example without the flag:

[root@potent-image ~]# puppet resource service made_up_service ensure=running
Error: Systemd start for made_up_service failed!
journalctl log for made_up_service:
-- No entries --

Error: /Service[made_up_service]/ensure: change from 'absent' to 'running' failed: Systemd start for made_up_service failed!
journalctl log for made_up_service:
-- No entries --
[root@potent-image ~]# echo $?
0

LGTM, could you squash the last two commits? Something like this should do the trick

git reset HEAD^
git add lib/puppet/application/resource.rb
git commit --amend
