/**
 * Abstract client that calls commandable AWS Lambda Functions.
 *
 * Commandable services are generated automatically for [[https://pip-services3-node.github.io/pip-services3-commons-node/interfaces/commands.icommandable.html ICommandable objects]].
 * Each command is exposed as action determined by "cmd" parameter.
 *
 * ### Configuration parameters ###
 *
 * - connections:
 *     - discovery_key:               (optional) a key to retrieve the connection from [[https://pip-services3-node.github.io/pip-services3-components-node/interfaces/connect.idiscovery.html IDiscovery]]
 *     - region:                      (optional) AWS region
 * - credentials:
 *     - store_key:                   (optional) a key to retrieve the credentials from [[https://pip-services3-node.github.io/pip-services3-components-node/interfaces/auth.icredentialstore.html ICredentialStore]]
 *     - access_id:                   AWS access/client id
 *     - access_key:                  AWS access/client id
 * - options:
 *     - connect_timeout:             (optional) connection timeout in milliseconds (default: 10 sec)
 *
 * ### References ###
 *
 * - <code>\*:logger:\*:\*:1.0</code>            (optional) [[https://pip-services3-node.github.io/pip-services3-components-node/interfaces/log.ilogger.html ILogger]] components to pass log messages
 * - <code>\*:counters:\*:\*:1.0</code>          (optional) [[https://pip-services3-node.github.io/pip-services3-components-node/interfaces/count.icounters.html ICounters]] components to pass collected measurements
 * - <code>\*:discovery:\*:\*:1.0</code>         (optional) [[https://pip-services3-node.github.io/pip-services3-components-node/interfaces/connect.idiscovery.html IDiscovery]] services to resolve connection
 * - <code>\*:credential-store:\*:\*:1.0</code>  (optional) Credential stores to resolve credentials

 *         ...
 *     }

 *     let client = new MyLambdaClient();
 *     client.configure(ConfigParams.fromTuples(
