Swagger file: SOL005NSLifecycleManagement_def.yaml; ns_lcm_op_occ: "statusEnteredTime" should be "stateEnteredTime" to match vnf_lcm_op_occ

The file https://forge.etsi.org/rep/nfv/SOL005/blob/v2.7.1/src/SOL005/NSLifecycleManagement/definitions/SOL005NSLifecycleManagement_def.yaml NsLcmOpOcc has "statusEnteredTime" misspelt.

It should ideally be "stateEnteredTime" to match the corresponding field in VnfLcmOpOcc: https://forge.etsi.org/rep/nfv/SOL002-SOL003/blob/v2.7.1/src/definitions/SOL002SOL003VNFLifecycleManagement_def.yaml

Reference: Attached screenshot from 2.7.1 SOL005 Spec.

The description against 'statusEnteredTime' says, "Date-time when the current state has been entered." Please see that it's referred to as "state" in the descriptions and other field names from NsLcmOpOcc as well, e.g. {'operationState'}. Apart from the specification language aspect, we have the below challenge from implementation and client side.

The dissimilarity of the names in SOL005 and corresponding SOL003/SOL002 model attributes may pose limitations when it comes to client-side/server-side code trying to use the JSON-Object-mapping tools (e.g. ObjectMapper) for invoking/serving APIs across NS and VNF LCM operations. The ObjectMappers need to have field transformation logic (to-and-fro) to map "statusEnteredTime" to "stateEnteredTime" and back while moving between the SOL003 and SOL005 APIs for instance.
