/**
 * A tool that wraps a RestApiTool to interact with a specific Application Integration endpoint.
 *
 * This tool adds Application Integration specific context like connection
 * details, entity, operation, and action to the underlying REST API call
 * handled by RestApiTool. It prepares the arguments and then delegates the
 * actual API call execution to the contained RestApiTool instance.
 *
 * * Generates request params and body
 * * Attaches auth credentials to API call.
 *
 * Example:
 * ```
 *   // Each API operation in the spec will be turned into its own tool
 *   // Name of the tool is the operationId of that operation, in snake case
 *   const operations = operationGenerator.parse(openApiSpecDict);
 *   const tool = operations.map(op => RestApiTool.fromParsedOperation(op));
 * ```
