Fix all the issues (A, B, C and D) in Dublin release

Keep it without any fix, and only correct them when designing the new target internal DM (TIDM):

• The rules for designing TIDM have to be considered and decided in Dublin release, e.g.,

Issue A and B1 have to be avoid
B2 should align with the SOL001 spec
C should be obsoleted and replaced by TIDM or other on-boarding DM (e.g. SOL001)
D should be obsoleted and replaced by TIDM or other on-boarding DM (e.g. SOL001)
Other rules?

• Provide guidance and suggestion for the related projects about using which TOSCA parser (SDC TOSCA Parser or NFV Parser).
