Allow a keep alive messages between fabric and chaincode. Default is no-keepalive.

Description

It is possible that an inactive gRPC connection between the chaincode and the peer can get broken by a intermediate proxy. Introduced a "keepalive" parameter (in seconds) which can be used to send ChaincodeMessage of type KEEPALIVE between the peer and chaincode. A chaincode just echoes the KEEPALIVE message received from the peer.

Motivation and Context

Keeps the connection between peer and chaincode going with application protocol level messages. This makes the connection liveness non dependent upon lower layer keepalive mechanisms.

Fixes #1850

How Has This Been Tested?

Enabled all chaincode tests (except one for covering no keep-alive scenario) to use an aggressive keepalive timer of 1 second.

@muralisrini It looks like this PR somehow contains additional commits that are not part of your change. Specifically, it looks like PR #1906 was included which is not part of the 0.5-developer-preview branch. Could you see if you can remove those?
