This is out of scope for this ADR.  Migrating an existing property to lazy types is being handled in a different way.

### Conventions

Once a new property has been introduced, you need to consider what its conventions will be.

    /**
     * Get the value of property as {@link String}.
     * @param propertyKey The key of the property. (NotNull)
     * @return The value of found property. (NotNull: if not found, exception)
     * @throws ConfigPropertyNotFoundException When the property is not found.
     */
    String get(String propertyKey);

    /**
     * Is the property true?
