fabric-go-sdk使用中的若干问题--连接e2e网络

### fabric-go-sdk使用中的若干问题--连接e2e网络

- problem

```bash

localhost:heroes-service liu$ go run main.go 

SDK created

Ressource management client created

Channel created

Channel joined

Initialization Successful

ccPkg created

Chaincode installed

Unable to install and instantiate the chaincode: failed to instantiate the chaincode: failed to get discovery service: could not get chConfig cache reference: load config items from config group failed: unsupported MSP type (1)

```

 [fabsdk/util] 2018/12/21 15:25:25 UTC - lazyref.checkTimeStarted -> DEBU ... finished handling expiration. Setting expiration to 1m30s

 [fabsdk/util] 2018/12/21 15:25:25 UTC - lazyref.checkTimeStarted -> DEBU Got closed event. Exiting timer.

```

- 解决办法

  这里因为demo，只用到了org1,并且只配置了org1,但是e2e 网络中存在org1 org2 org3,及缺少了org2、org3的配置，变出错了；

  解决：清理，configtx.yaml 和crypto-config.yaml 中的无用组织的内容，改问题消失
