For the purpose of managing an already existing database with pgroll, provide a tool that initiates a baseline migration and enables pgroll on the database.

Tasks

• Implement a (hidden) pgroll baseline command that creates a new baseline type migration in pgroll.migrations.
• Ensure that the start , complete, rollback workflow works when the parent migration is a baseline migration.
• Update pull command to not pull anything before and including the most recent baseline migration.
• Update the migrate command to not try to apply baseline migrations and not fail on mismatched migrations prior to the most recent baseline version.
• Implement the improvements to pull and migrate (🕊️ Updates to pull and migrate commands).
• Test the ability to have multiple baselines in a migration history.
• Add documentation to pgroll.com/docs
• Un-hide the pgroll baseline command
