Added alias support in model parsing. Also added searching for "sources" yml blocks pushing table/column documentation to metabase (defining sources is recommended by dbt best practices and often done in tandem with creating staging models). Allows using "metabase.fk_ref" in sources or models .yml in order explicitly define a metabase relationship to a table which allows us to propagate the FK relationship properly to Metabase regardless of aliasing. metabase.fk_ref is looked for first in meta before falling back to default parser.

Replace print with log and ensure multiple sources in a single YML can be looped through- also formatted according to black

replace single quoting with double to conform to style guideline

useful when project structure is defined and ymls created but not yet populated

replaced last prints with info level logs and made invalid yml logger msg match rest

Re-added processing model logger info msg

updated log to match recommendation
