 * Made the new load balanced bare-metal node the default one for mainnet (it is called `lb`). The legacy one (load balanced k8s node) is called `lb_k8s`

 * Refactor Composer to be created with all the markets and tokens. The Composer now uses the real markets and tokens to convert human-readable values to chain format

 * Change in AsyncClient to be able to create Composer instances for the client network, markets and tokens
