[FEATURE] Add dedicated name for CF environment

[sdischer-sap]

Is your feature request related to a problem? Please describe.
When creating a CF Environment via the BTP Provider, the 'name' attribute from 'metadata' is being used as the CF 'org-name'. This is a problem, because this 'org-name' must be unique within probably the whole global account.
Therefore the tutorial is not working properly out of the box.

This requires a more solid concept first, but we can already describe here what the expectation is.

Describe the solution you'd like

• Removed binding between 'org-name' and the 'metadata' 'name'
• Create new parameter/uuid for defining the 'org-name' and instance name
• Analysis of existing tests (Unit and Integration)
• make sure schema is compatible and existing resources can be "upgraded"

Additional context
We might need to experiment with the api a bit to better understand whats the difference of org-name, instanceName and environment name is and how to set it.
