Refactor chaincode commit

[bestbeforetoday]

• Consistency with chaincode install, queryinstalled, and approve
• Use fabric-gateway to simplify implementation
• Use correct install script for samples and test-network.
• Remove channel creation using API from e2e test since it does not configure anchor peers.

I hope we can clean up useless comments before merge. Or you can go ahead with merge it then we will have another PR for clean up.

I have merged so other changes can be based on top of it. It would be good to have a follow-up PR that takes the channel configuration test code I had to comment out and perhaps moves it to a separate end-to-end test, which configures another channel. That would allow the chaincode deployment and channel config code to both continue being tested until anchor peer configuration is added so we have a complete end-to-end capability.

If it is possible to configure anchor peers with the current implementation, then please do go ahead and add that into the end-to-end test code and we can go back to using the channel config API instead of having the network.sh script create the channel.
