8.0.0 - 5.x compatibility + container_name mandatory

What's Changed

• Upgrade to 5.x + Fixes by @Ohid25 in #74

BREAKING CHANGE
container_name now must be set for target_group.

This variable can be set via var.container_name or can be set via var.name_prefix.

The purpose behind this change is to accommodate the requirement of using an external container definition where the container name(s) are set externally to the module and, therefore, must be set within target_group.

Please refer to any of the examples to understand this change.
