Changes to Travis

• bump travis nodeJS level to 10

Changes to bindings

• Bump ethereum web3 level to 1.2.2
• Align fabric SDK bindings to the version of SDK (fabric-network removed from early bindings)

Changes to integration test:

• Add additional phase for binding to Fabric v2.1.0 SDK
• Add target peer specification to query benchmark
• Add explicit phase resources for gateway based tests
• Modified Besu docker compose file

Changes to messenger:

• There was an MQTT error on disconnect resulting in a hanging process, which was undetected previously due to only having a single test run. Not forcing the close and passing an empty Options object instead of undefined solved this and allows the benchmark to complete correctly

Logging:

• In hunting for the above error, I added some more logging on key phases. Makes sense to leave these in

Buffer:

• Instances of new Buffer replaced with Buffer.from() to get rid of the security warnings

worker-orchestrator:

• removed the redundant killing of processes in the this.workerObjects array, since we now clean up workers within the messenger with a process.exit(0) in the message handler

Fabric.js

• Switch on the version to use is now performed on the installed version of the fabric-network package, and not the fabric-client. This proved more stable within the integration tests
• Ensure gateway use of V1 can only occur on versions where the required default strategies exists (1.4.2 and above)

Fabric-Gateway-v1:

• Actually set a peer cache so that target peers may be used, but warn and skip this on versions that cannot set target peers on transactions (must be 1.4.5 and greater)
• Rename passed arg transientData to transientMap to match docs
• Override the query timeout on the gateway

Fabric-Gateway-v2:

• Logging mod provided for view purposes (happy to revert)
• Performs validation after variable setting for discovery option
• Rename passed arg transientData to transientMap to match docs
