* Migrations in place, how to run them? * Remove down migrations and touch database.go * Database and Database Test package in place, added functions to get and store app metrics * make generate output * Minor bug fix on app metrics insert and select * Add a validation layer to restrict what can be saved in the database * Make validation more terse, throw error if schema doesn't exist, expose appmetrics service * service updates * Compute all errors before sending them out * Trying to bring a closjure to appmetrics go * Expose appmetrics via an api, skip fancy * Address value as Jason Dawt Rawmasage to ease parsing * Introduce a buffered chan with magic cap of 8 to minimize writes to DB. Tests for service and API. Also expose GetAppMetrics function. * Lint issues * Remove autoincrement, undo waku.json changes, fix error being shadowed, return nil where nil ought to be returned, get rid of buffered channel * Bump migration number * Fix API factory usage * Add comment re:json.RawMessage instead of strings * Get rid of test vars, throw save error inside the loop * Update version Co-authored-by: Samuel Hawksby-Robinson <samuel@samyoul.com>
