Variable naming conventions

[widhalmt]

The newest version of ansible-lint says, variables within roles should use the role name as a prefix.

For the most part we already stick to that rule. But we have a bunch of variables that are global to the whole collection. They are mostly used for interaction between the roles in the collection. These are prefixed with elastic_.

How should we deal with this new rule?

• Just put an exception into the ansible-lint configuration?
• Rename the variables so that they are local to every role? If we need interaction we need a lot of set_fact for synchronization.
• Come up with a completely different solution?
• Find a way to have "global variables" in collections? A short search didn't reveal any option to do that.

I opened a discussion upstream ( https://github.com/ansible/ansible-lint/discussions/3451 ) to get a viable solution. Thanks @dgoetz for suggesting.
