Anna Stuchlik d0bae532bd doc: move cloud deployment instruction to docs -v2 
This is V2 of https://github.com/scylladb/scylladb/pull/14108

This commit moves the installation instruction for the cloud from the [website ](https://www.scylladb.com/download/)to the docs.

The scope:

* Added new files with instructions for AWS, GCP, and Azure.
* Added the new files to the index.
* Updating the "Install ScyllaDB" page to create the "Cloud Deployment" section.
* Adding new bookmarks in other files to create stable links, for example, ".. _networking-ports:"
* Moving common files to the new "installation-common" directory. This step is required to exclude the open source-only files
in the Enterprise repository.

In addition:
- The Configuration Reference file was moved out of the installation
  section (it's not about installation at all)
- The links to creating a cluster were removed from the installation
page (as not related).

Cloud Instance Recommendations for AWS, GCP, and Azure

:title:
:description: Cloud Instance Recommendations for AWS, GCP, and Azure
:keywords: ScyllaDB Cloud deloyment, AWS, GCE, Azure, ScyllaDB image, cloud instance, cloud support
You can run your ScyllaDB workloads on AWS, GCE, and Azure using a ScyllaDB image. This page includes the recommended instance types to be used with ScyllaDB.
.. TO DO: Add a link to the installatation section for cloud deployments - when the page is added.
.. note::
The following recommendations apply to self-managed deployments. See the `ScyllaDB Cloud documentation <https://cloud.docs.scylladb.com/>`_ to learn about ScyllaDB's fully managed database-as-a-service.
.. _system-requirements-aws:
Amazon Web Services (AWS)
-----------------------------
* The recommended instance types are :ref:`i3 <system-requirements-i3-instances>`, :ref:`i3en <system-requirements-i3en-instances>`, and :ref:`i4i <system-requirements-i4i-instances>`.
* We recommend using enhanced networking that exposes the physical network cards to the VM.
.. note::
Some of the ScyllaDB configuration features rely on querying instance metadata.
Disabling access to instance metadata will impact using Ec2 Snitches and tuning performance.
See `AWS - Configure the instance metadata options <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-options.html>`_ for more information.
.. _system-requirements-i3-instances:
i3 instances
^^^^^^^^^^^^
This family includes the High Storage Instances that provide very fast SSD-backed instance storage optimized for very high random I/O performance and provide high IOPS at a low cost. We recommend using enhanced networking that exposes the physical network cards to the VM.
i3 instances are designed for I/O intensive workloads and equipped with super-efficient NVMe SSD storage. It can deliver up to 3.3 Million IOPS.
An i3 instance is great for low latency and high throughput, compared to the i2 instances, the i3 instance provides storage that it's less expensive and denser, along with the ability to deliver substantially more IOPS and more network bandwidth per CPU core.
