forcing usage of luseradd/lgroupadd broke some distros

[jewnix]

Some distros either don't have the luseradd and lgroupadd commands, or they are just broken.

This sets the local: false as the default (since this is how it has been before the recent change).
If you wish to force to create local user and group, set the local_os_user and local_os_group to true.

Good catch - super weird that ansible decides to use luseradd and doesn't have any fallback for systems which don't have that command, but that's an issue with ansible core not the splunk role. Thanks for this!
