Validate plentyone credentials

Probe a PlentyONE host/username/password without persisting a connection, returning the one synthetic system entity available under them. Returns 400 if authentication or the host fails to resolve. A multi-org credential must send an `Organization-Id`, `Connection-Id` or `Entity-Id` selector, or gets a 400.

Category: Connections
