RemotePlatform should cache common deployment artifacts

[brianoliver]

When deploying a number of processes to the same RemotePlatform, many/most of the deployed artifacts are the same files. It doesn't make sense to copy them individually for each application being launched. Instead we should be able to simply cache (use one copy) of common files.

eg: copy a common non-snapshot files into /tmp/oracle-bedrock/cache/ or in ~/.bedrock/cache

and then use the common files when establishing the classpath.
