healthchek mechanism based on DB connection

Service health check mechanism
Service that includes connection to DB should depend on his healthcheck interval checking based on DB connection

Good reference on how it should implemented:

based on auth-manager

const healthCheck = (connection: DataSource): HealthCheck => {
  return async (): Promise<void> => {
    const check = connection.query('SELECT 1').then(() => {
      return;
    });
    return promiseTimeout<void>(DB_CONNECTION_TIMEOUT, check);
  };
};
