[ndnSIM] [EXT] Modifying trust schema/trust model in ndnSIM

[Junxiao Shi]

Hi Meban

It's possible, but trust schema is not the strong suit of ndn-cxx, the NDN
library used by ndnSIM.
Specifically, ndn-cxx only has trust schema validator (it's called
ValidatorConfig), but lacks trust schema signer.

ndnSIM is most suitable for simulating a network of many nodes, with models
that represent network links with proper timing and loss probability.
If you don't need these models, it's faster to prototype with Python or
TypeScript.

Yours, Junxiao
