Split object store and data lake consistently

[tvogels01]

We should move to where:

• "object store" is a bucket in S3 where all the code (schemas, jars, ...) and configuration (config) lives
• "data lake" is a bucket in S3 where all (transient) data lives
  • data which is exported from upstream databases
  • data that is landed by other systems and is pulled in through Redshift Spectrum
