Config - Allow recursive glob patterns to get files subdirectories

[Cikmo]

Is your feature request related to a problem? Please describe.
Currently, if you override the default schema_paths in db.migrations, it is not possible to get a recursive coverage in ./schemas. Glob patterns like ./schemas/**/*.sql only works one level deep.

Describe the solution you'd like
Allow recursive glob pattern such that, for example, ./schemas/**/*.sql would cover every subdirectory of ./schemas more than one level deep.
