JNI libs and code execution

When installing Lenses on a linux instance, it is recommended to mount the /tmp folder without the noexec flag.

If you mount your /tmp directory with the noexec flag, please review the Lenses documentation on how to set up snappy and JNI to point to another folder.

Failing to do the above, will result into Lenses or any other JVM application on that host, to not be able to read records compressed with snappy and might also cause issues in streaming SQL queries as the JVM will not be able to utilize rocksdb options.
