Running multiple instances of Snowflake

The main difference between the param-search endpoint and the snowflake endpoint is that param-search queries the database and runs different batches. Each batch consists of possible combinations of parameters given by the input toml.

An input of a search params config is the same as the one for snowflake but with the added arrays of parameters that give more than one option for some parameters.
