I don't think we should be doing this:

"github.com/hyperledger/fabric/v2/bccsp"
"github.com/hyperledger/fabric/v2/common/flogging"

Fabric core is not supposed to be imported by external projects as a go module. No one promises you anything about its packages not undergoing radical changes.

Hi @yacovm , let's discuss at #3464 and for this PR. I am going to close it for now. As this pr is just a sample for open v2 modules. I want to have a single thread for discussion, instead of both PR and issue.
