This PR adds preliminary parsing of parameters. Currently it only supports 4 types: string, int, float32, and bool. Almost certainly we will need to introduce more complicated parsing configuration (to handle objects and arrays), but my initial attempts got quickly complicated, so I simplified in the short term. This also makes 2 breaking changes to config.yaml: - changes "parameters" to be a list over object -- this is because parameter ordering is important, and needs to be preserved - removed the "required" field from parameter objects -- we need to determine how to handle optional parameters in SQL queries
