Add Google Gemini Component, improvements and bugfixes (#1243)

This release of Langflow introduces a range of enhancements and notable
new features aimed at improving functionality, code quality, and user
experience. Key updates include the introduction of the Google Gemini
Component, a pivotal addition that expands the capabilities of Langflow
in language model applications.

Significant improvements were made in the custom component
functionality, notably in the areas of serialization and validation.
Basic support to LangChain Runnables added to the `process` endpoint.

On the front end, we've implemented changes to improve the overall user
interface and interactions. These include updates to the GenericNode
component, adjustments in the UI for better handling of nodes in the
flow, and the addition of new icon components for a more intuitive user
experience.

Backend refinements include updates to the Anthropic LLM and FAISS
component, along with several bug fixes and code optimizations. These
changes enhance the stability and efficiency of Langflow.

+Auroraのシークレットは [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/?nc2=type_a) によって管理されます。
+Fargate のタスクはフロントエンドとバックエンドに分かれており、サービス検出によって通信します。
+リソースをデプロイするだけであれば、上記の各サービスについて深い知識は必要ありません。

+# Deploy Langflow on AWS
+
+**Duration**: 30 minutes
+
+## Introduction
+
+In this tutorial, you will learn how to deploy langflow on AWS using [AWS Cloud Development Kit](https://aws.amazon.com/cdk/?nc2=type_a) (CDK).
+This tutorial assumes you have an AWS account and basic knowledge of AWS.
+
+The architecture of the application to be created:
+![langflow-archi](./img/langflow-archi.png)
+
+[Application Load Balancer](https://aws.amazon.com/elasticloadbalancing/application-load-balancer/?nc1=h_ls), [AWS Fargate](https://aws.amazon.com/fargate/?nc2=type_a) and [Amazon Aurora](https://aws.amazon.com/rds/aurora/?nc2=type_a) are created by AWS CDK.
+The aurora's secrets are managed by [AWS Secrets Manager](https://aws.amazon.com/secrets-manager/?nc2=type_a).
+The Fargate task is divided into a frontend and a backend, which communicate through service discovery.
+If you just want to deploy resources, you do not need in-depth knowledge of each of the above services.
+
+# How to set up your environment and deploy langflow
+
+1. Open [AWS CloudShell](https://us-east-1.console.aws.amazon.com/cloudshell/home?region=us-east-1).
+1. Run the following commands in Cloudshell:
+   ```shell
+   git clone https://github.com/aws-samples/cloud9-setup-for-prototyping
+   cd cloud9-setup-for-prototyping
+   ./bin/bootstrap
+   ```
+1. When you see `Done!` in Cloudshell, open `cloud9-for-prototyping` from [AWS Cloud9](https://us-east-1.console.aws.amazon.com/cloud9control/home?region=us-east-1#/).
+   ![make-cloud9](./img/langflow-cloud9-en.png)
+1. Run the following command in the Cloud9 terminal.
+    ```shell
+    git clone -b aws-cdk https://github.com/logspace-ai/langflow.git
+    cd langflow/scripts/aws
+    cp .env.example .env # Edit this file if you need environment settings
+    npm ci
+    cdk bootstrap
+    cdk deploy
+    ```
+1. Access the URL displayed.
+   ```shell
+   Outputs:
+   LangflowAppStack.NetworkURLXXXXXX = http://alb-XXXXXXXXXXX.elb.amazonaws.com
+   ```
+1. Enter your user name and password to sign in. If you have not set a user name and password in your `.env` file, the user name will be set to `admin` and the password to `123456`.
+   ![signin-langflow](./img/langflow-signin.png)
+
+# Cleanup
+
+1. Run the following command in the Cloud9 terminal.
+   ```shell
+   bash delete-resources.sh
+   ```
+1. Open [AWS CloudFormation](https://us-east-1.console.aws.amazon.com/cloudformation/home?region=us-east-1#/getting-started), select `aws-cloud9-cloud9-for-prototyping-XXXX` and delete it.
