etcd client upgraded, gson level upgraded

Why ?

The wrong level of gson was being bundled in the etcd cps extension.
Also, lots of the other jars were very down-level and old.

Uplift the embedded transitive dependencies in the etcd cps extension jar, and explain how
to do that to others.

How tested ?

• Docker images of dex, couchdb and etcd running in the background.
• Started the api server
• Started the web UI application.
• Got a token from the web ui
• Configured that into the command-line tool
• Can use galasactl properties set --namespace mike --name mike.prop1 --value hello to set a CPS property
• Can use galasactl properties get --namespace mike to query it back again.
• Conclusion: etcd is being used to store the values as before. OK.
