Added smart contract to store mapping between legacy and new DID/Schema/CredDef identifiers

@@ -4,68 +4,92 @@ The idea is using of a basic mapping between legacy DIDs identifiers and ethereu
 `did:indy2` DID method.  
 So that legacy DID can be associated with a new `did:ethr` and we can only use `did:ethr` in the network.
