device-roaming-status-subscription: TerminationReason missing enums

[akoshunyadi]

Problem description TerminationReason doesn't have the values MAX_EVENTS_REACHED and ACCESS_TOKEN_EXPIRED They seem to be forgotten.

Possible evolution Add missing enums:

• MAX_EVENTS_REACHED - Maximum number of events (optionally set by the requester) has been reached
• ACCESS_TOKEN_EXPIRED - Access Token sinkCredential (optionally set by the requester) expiration time has been reached
