Java SDK - Pass private data collection definitions during chaincode instantiation

Gerrit CR https://gerrit.hyperledger.org/r/#/c/22091/

Java SDK - Pass private data collection definitions during chaincode instantiation.

When using CLI, this is done by passing a JSON file which includes collection definition:

--collections-config collections.json

Where a sample JSON file content is:

[
 {
     "name": "collectionMarbles",
     "policy": "OR('Org1MSP.member', 'Org2MSP.member')",
     "requiredPeerCount": 1,
     "maxPeerCount": 2,
     "blockToLive":1000000
},
 {
     "name": "collectionMarblePrivateDetails",
     "policy": "OR('Org1MSP.member')",
     "requiredPeerCount": 1,
     "maxPeerCount": 1,
     "blockToLive":3
 }
]

 
CLI passes collection config upon chaincode instantiate, see: https://gerrit.hyperledger.org/r/#/c/14371/
 
In CLI, collection JSON is converted to CollectionConfigPackage proto:
https://github.com/hyperledger/fabric/blob/release-1.1/protos/common/collection.proto#L16-L50
and then marshaled and passed to LSCC as an argument.
 
LSCC accepts collection config as an argument and stores it, see: https://gerrit.hyperledger.org/r/#/c/14291/
