Adds configuration management through YAML

Depends on https://github.com/asascience-open/ooi-ui-services/pull/23

- `ooiservices.config` is a dynamic module that is loaded from a package resource (`ooiservices/config/config.yml`)
- Configuration can be dynamically reloaded
- YAML is easier to read than `ini` in my opinion.
- Top level configurations become variables in the config module
does this satisfy the SQLiteAdaptor import? Could I configure the name of the class import in the ini file?
