2128/confirm prompt validator not invoked as expected

[longieirl]

Fix for #2128

• The confirm SCP prompt has a validator method attached which is not invoked for all flows i.e. CLI and YUI, refer to inquirer API. However, the abap-inq was written as if this validator was invoked for both YUI and CLI. This PR removes the validator method and ensures the scp prompt state is maintained correctly by adding a scp setter prompt to handle both flows, CLI and YUI.
• If the user selects a SAP system, the client prompt will no longer be shown, this causes issues with the connectivity flow if the user tries to switch client ID's as then the saved system properties will not be used
• Tests added
• Validated locally on VSC and on BAS
