Determine all supported configuration options to a Syndesis deployment

For 7.5, all Fuse Online configuration changes are made through (and enforced by) the operator.

In previous versions, users were potentially able to change any values in the config maps read by syndesis. This is no longer possible and any changes will need to go into the Custom Resource.

We need a list of all configuration changes a customer is expected or allowed to make, so that we may verify those are implemented in the CR and read by the operator.
