SMP specification 1.2.0: Check ServiceActivationDate/ServiceExpirationDate

[Florianisme]

As far as I am aware, the fields ServiceActivationDate and ServiceExpirationDate returned in the response from the SMP when querying an endpoint are ignored as of now.
As of version 1.2.0 of the SMP it was clarified that they should be checked for validity and the connection to that endpoint should be refused when they are not valid yet/anymore.

I guess it should be a check in the SMPClientReadOnly class in the getEndpoint() Method. I can try to add it myself if you have not planned anything yet.

Can you move the issue?

As this change is only due at May 1st, 2022 I have some time to get this done.
Key point will be, that the LocalDateTime und question needs to be added to the API.
It will be done soon
