metadata_handler

Metadata will be an important component for allowing TriggerKit to make and react to interactive messages.

We need to allow users to: - encode metadata in their messages - retrieve metadata from user interactions in the Snowflake Table

The means tk_slakc needs to: - Encode the specified metadata into the message - Retrieve the metadata from messages - Send the metadata with the user interaction to Snowflake
