Local user interaface for Airavata MFT

Currently, Airavata MFT can be accessed through its command line interface and the gRPC API. However, it is really easy if a [Docker desktop](https://www.docker.com/products/docker-desktop/)-like user interface is provided for a locally running Airavata MFT. The functionalities of such an interface can be summarized as follows

1. Start / Stop MFT Instance
2. Register/ List/ Remove Storage endpoints
3. Access data (list, download, delete, upload) in configured storage endpoints
4. Move data between storage endpoints
5. Search data across multiple storage endpoints
6. Analytics - Performance numbers (data transfer rates in each agent)

We can use [ElectonJS](https://www.electronjs.org/) to develop this cross-platform user interface. The node.js backend of ElectronJS can use gRPC to connect to Airavata MFT to perform management operations
