Allow more flexible baselines?

[srcshelton]

In Flyway, baselineDescription ('<< Flyway Baseline >>') is configurable - although again looking more likely to lead to mass-breakage than to actually be a useful tunable.

Alongside, baselineVersion defaults to '1'. We instead default to zero, but this can be overridden by providing an argument to --init, and it also taken from the first schema-file encountered.

Should it be possible to configure a database in schema.conf for which there are no schema-files present, but where a baseline version is specified? This database would then be created with metadata but no further content.

I use-case might be to give a database baseline 'unmanaged', which would ensure that the database exists but would prevent further automated deployment to it - as opposed to having a database with a baseline schema-file only, which would allow higher-versioned schema to be added in the future.

Now massively useful, but it's a thought...
