Standardized project structure

Details:
- Documentation folders refactored to mirror 'standard' organization.
- DocsGenerator removed to let default Tomcat servlet serve
  documentation
- Added DocsRedirectFilter to redirect all the GETs to /docs and
  /api-docs to their index.html pages
- Added CHANGELOG file

+# Docker Instruction
+
+Instruction to generate e run storagehub docker image 
+
+## Dockerfile - DokerCompose
+
+This image is ready to be deployed in a new environment.
+The Dockerfile generate an image without configurations (container, service etc.), all the configurations must be provided at image start time.
+In fact the docker-compose.yml requires 3 environmental variables set at start time: APP_PORT, JACKRABBIT_FOLDER, CONTAINER_SERVICE_FILE_FOLDER.
+
+```
+APP_PORT=8080 JACKRABBIT_FOLDER=/data/jackrabbit CONTAINER_SERVICE_FILE_FOLDER=/etc/smartgears-config docker compose up
+```
+
+## Dockerfile - DokerCompose standalone
+
+The image generated from Dockerfile-standalone contains all the configuration to run on a fully isolated container.
+The docker-compose-standalone.yml contains the declaration of all the services needed (postgres and minio) teking all the configuration from the local ./docker folder
+
+```
+docker compose -f docker-compose-standalone.yml up
+```

+Introduction
+============
+
+StorageHub is a versatile service designed to provide seamless access
+to various storage resources, ensuring data persistence and management. It acts
+as an intermediary layer that can interface with any underlying storage
+solution, such as Amazon S3 or MongoDB, offering a unified and flexible approach
+to storage management.
+
+Base URL
+--------
+
+In the production environment, its current value is https://api.d4science.org/
+
+Key Features
+------------
+
+Flexibility and Integration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+StorageHub is designed to be highly flexible, allowing it to serve as an
+intermediate layer for diverse storage solutions. This flexibility ensures that
+it can adapt to different storage backends without requiring significant changes
+to the applications that rely on it.
+
+RESTful Interface
+~~~~~~~~~~~~~~~~~
+
+StorageHub exposes a RESTful API, which allows any application capable of making
+HTTP requests to access it. This REST interface provides a standardized way to
+interact with the storage resources, enabling easy integration with various
+applications and services. See the available REST-API on `StorageHub API docs
+<../api-docs/index.html>`_.
+
+Metadata Management
+~~~~~~~~~~~~~~~~~~~
+
+StorageHub leverages a JackRabbit-based object store to manage all metadata
+associated with the stored data. This ensures that metadata is efficiently
+organized and easily retrievable, enhancing the overall data management
+capabilities of the service.
+
+Direct Payload Storage
+~~~~~~~~~~~~~~~~~~~~~~
+
+While metadata is handled by JackRabbit, the actual data payloads are stored
+directly on the underlying storage solutions. This approach optimizes storage
+efficiency and performance, ensuring that large data payloads are managed
+effectively.
+
+Primary Use Cases
+-----------------
+
+Workspace
+~~~~~~~~~
+
+The main application that interacts with StorageHub is the Workspace portlet,
+which is easily accessible from the Virtual Research Environments (VREs). The
+Workspace provides a "standard" HTML interface where users can perform all the
+common operations available in a file system, such as creating, reading,
+updating, and deleting files and directories.
+
+In addition to these standard file system operations, the Workspace offers
+features that are specific to VREs. These include publishing on the Catalogue,
+sharing resources with other users, and managing versions of files. These
+capabilities make the Workspace a versatile tool for managing data within the
+VREs, leveraging the services provided by StorageHub.
+
+Java Client
+~~~~~~~~~~~
+
+The methods of the Web Service can be called by writing your own REST client
+application or by using already existing REST client plugins.
+
+In case of a Java client, we provide the StorageHub Client Library, which is a
+Java library designed to facilitate seamless interaction with StorageHub. It
+abstracts the complexities of the REST API, providing a more intuitive and
+convenient interface for Java developers.
+
+The StorageHub Client Library allows developers to easily integrate StorageHub's
+capabilities into their applications without dealing with the intricacies of
+HTTP requests and responses. The library handles all the necessary communication
+with StorageHub, allowing developers to focus on their application's core
+functionality.
+
+.. tip:: If you're coding in Java, it is recommended that you include the
+   StorageHub Client Library into your project.
+
+Authorization
+-------------
+
+D4Science adopts state-of-the-art industry standards for authentication and
+authorization. Specifically, the implementation fully adopts `OIDC (OpenID
+Connect) <https://openid.net/connect>`_ for authentication and UMA 2 (User
+Managed Authorization) for authorization flows. `JSON Web Token (JWT) Access
+token <https://jwt.io/>`_ are used for both authentication and authorization.
+
