Support overriding test element properties from user.properties

### Use case

There might be a need to override some of the properties based for a specific environment, or for a specific test launch.

Currently, users can manually put `${...}` expressions, however, they do need to provision the expressions in advance.

### Possible solution

Implement a naming convention so users can craft properties that override values in the components.

For instance: `components....=`

Open questions:
* Do we need to have a stable component ids or can we rely on the names?
* How do we handle "collection" properties? For instance, should be have separate syntax for "add", "remove", and "replace" operations?
