Issue 391: Update Pravega library versions and deployment script

[RaulGracia]

Change log description
Updates Pravega libraries and deployment scripts.

Purpose of the change
Fixes #391.

What the code does

• Updates Pravega and Bookkeeper versions at the server side when deploying, as well as the Pravega client library for the benchmark.
• Updates the AMI used and the default types of images.
• Updates the deployment script to adapt to few changes: i) docker installation, ii) cloudalchemy.node_exporter naming, iii) device names, iv) Bookkeeper initialization command.
• Updated the README to reflect previous changes.
• Set scope provided to driver-nats-streaming. The reason for doing that is that driver-nats-streaming is transitively importing a very old version of Google Protobuf (3.9.1 - Aug 06, 2019). Pravega also uses Google Protobuf. When upgrading Pravega, we found a NoSuchMethodError related to Google Protobuf and the reason was that the newer Pravega version are compiled with a more recent Google Protobuf version with incompatible changes (since version 3.17.2). Having both Google Protobuf versions in the classpath leads to runtime errors, so I decided to prevent the oldest Google Protobuf version to be transitively imported by driver-nats-streaming. Given that NATS Streaming has been deprecated, I feel that it is a safe action to do (which can precede the removal of NATS Streaming until NATS JetStream is available).

How to verify it

• Build is passing.
• I can run the benchmark locally against Pravega standalone.
• I have deployed Pravega on AWS and executed the benchmark successfully.

Hi @merlimat, yes this change is intended. I tried to explain the justification in the PR description:
