Create a config.yaml file when database server is first run

[zachmu]

This is standard practice in the database world: you get a config file with the defaults when you install the server.

https://www.postgresql.org/docs/current/config-setting.html#CONFIG-SETTING-CONFIGURATION-FILE

Dolt makes you write your own.

Instead, Dolt should drop a config.yaml file with the default values (modified as necessary for the current execution) in the same location as the database directories when sql-server is run.

Same goes for config.json. It is mentioned in the docker instructions mapping host directories to docker directories but no standard template is provided anywhere.

Thanks for the feedback, agree we could do better here.
