Introduce "no command message support" flag for protocol adapters in the Tenant API

[sysexcontrol]

A new flag to handle a "no command-message" must be introduced in the Tenant API as part of the Adapter Configuration Format. See #654 for details.

The flag will be used by specific protocol adapters to derive that a request will not have to wait for potential commands anymore and can instead be responded directly after receiving such a message.

The default shall be false.

The handling of this flag inside a protocol adapter is not part of this issue, only the definition (and possibly the implementation of helper methods to evaluate this flag).
