Go SDK for Fabric

NOTE: Due to namespace conflict between fabric-protos-go and fabric-protos-go-apiv2, use GOLANG_PROTOBUF_REGISTRATION_CONFLICT=warn flag when using go-sdk at runtime.

Integration tests for `asset-exchange` using go-sdk

To run integration tests:

First, launch a pair of test networks, one of which must be a Fabric network.
Next, navigate to the Go CLI folder to run test scripts as per the below instructions.

Integration tests for data-sharing and asset-exchange are programmed in the file exerciseSDK.go. You can run this in either of the following ways:

Compile the source using go build -o ./bin/exerciseSDK exerciseSDK.go, and then run the executable ./bin/exerciseSDK.
Build and run the executable using go run exerciseSDK.go.

Before running the tests, please ensure that the below keys are populated appropriately in the network connection profile (e.g., in the network1 connection profile available at ../../../tests/network-setups/fabric/shared/network1/peerOrganizations/org1.network1.com/connection-org1.json).

keys in the connection profile `json` file: channels, orderers, certificateAuthorities

Sample content for the values of these keys can be found in the file helpers/testdata/example/peerOrganizations/org1.example.com/connection-tls.json (please note that the value of the key "certificateAuthorities"."ca.org1.example.com"."tlsCACerts"."pem" in this file is an array).

Also note that similar checks need to be carried out for the connection profile yaml file if you want to use the yaml file instead of json. Sample content for the values of these keys can be found in the file helpers/testdata/example/peerOrganizations/org1.example.com/connection-tls.yaml.

Testing membership manager functions

The membership manager functions are currently not covered by unit tests. As a temporary measure,below are instructions to test them in a standalone package as follows.

Build the go-sdk.
Start the Weaver testnet, e.g., by navigating to <cacti-root>/weaver/tests/network-setups/fabric/dev and running make start-interop-local.
From go-sdk, Run (replace <cacti-root> with path to the cacti clone):
```
  cd membershipmanager
  GOLANG_PROTOBUF_REGISTRATION_CONFLICT=warn CACTI_ROOT=<cacti-root> go test -v .
```
You should see membership contents in the output with no errors.

Configurations

Set the output of the below command as the value of the key "members"."Org1MSP"."value" in the file data/credentials/network1/membership.json (similarly for network2).

awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}' ../../../tests/network-setups/fabric/shared/network1/peerOrganizations/org1.network1.com/peers/peer0.org1.network1.com/msp/cacerts/localhost-7054-ca-org1-network1-com.pem
