Check for compatibility encryption compatibility

[spiegela]

Currently, there are no checks to evaluate if an encryption-enabled bucket instance could be created. If the customer defines a default namespace with encryption disabled, and then creates a service instance with encryption enabled, the bucket-create operation fails without a very instructive error message.

If the default namespace has encryption disabled, but the catalog contains an encryption-enabled service, IMO we should either:

1. Return an error within the tile configuration (not sure how to do this)
2. Crash during startup with an instructive error message
