Simplify Examples

[ghost]

Is your feature request related to a problem? Please describe.
When having a look at the examples, it is not clear right away, how a variable should look, because it is hidden away in a local. This is even worse in the README, as the local.tf is nowhere integrated.

Describe the solution you'd like
Remove locals completely from examples and hardcode the values.

Describe alternatives you've considered
The only upside of locals is, that you can reuse the values. But as examples are examples, there is no need to reuse values.

Furthermore the Network security rule has nothing to do with the module and should also be removed
