doc/start: remove "intro.rst"

Remove "start/intro.rst", which has been renamed "start/index.rst" in
order to follow the conventions followed elsewhere in the documentation.

Follows https://github.com/ceph/ceph/pull/57900.

- Intro to Ceph
-===============
-
-Ceph can be used to provide :term:`Ceph Object Storage` to :term:`Cloud
-Platforms` and Ceph can be used to provide :term:`Ceph Block Device` services
-to :term:`Cloud Platforms`. Ceph can be used to deploy a :term:`Ceph File
-System`.  All :term:`Ceph Storage Cluster` deployments begin with setting up
-each :term:`Ceph Node` and then setting up the network. 
-
-A Ceph Storage Cluster requires the following: at least one Ceph Monitor and at
-least one Ceph Manager, and at least as many :term:`Ceph Object Storage
-Daemon<Ceph OSD>`\s (OSDs) as there are copies of a given object stored in the
-Ceph cluster (for example, if three copies of a given object are stored in the
-Ceph cluster, then at least three OSDs must exist in that Ceph cluster).
-
-The Ceph Metadata Server is necessary to run Ceph File System clients.
-
-.. note::
-
-   It is a best practice to have a Ceph Manager for each Monitor, but it is not
-   necessary.

-            |      OSDs     | | Monitors   | |  Managers  | |      MDSs     |
-            +---------------+ +------------+ +------------+ +---------------+

-- **Monitors**: A :term:`Ceph Monitor` (``ceph-mon``) maintains maps of the
-  cluster state, including the :ref:`monitor map<display-mon-map>`, manager
-  map, the OSD map, the MDS map, and the CRUSH map.  These maps are critical
-  cluster state required for Ceph daemons to coordinate with each other.
-  Monitors are also responsible for managing authentication between daemons and
-  clients.  At least three monitors are normally required for redundancy and
-  high availability.
-
-- **Managers**: A :term:`Ceph Manager` daemon (``ceph-mgr``) is
-  responsible for keeping track of runtime metrics and the current
-  state of the Ceph cluster, including storage utilization, current
-  performance metrics, and system load.  The Ceph Manager daemons also
-  host python-based modules to manage and expose Ceph cluster
-  information, including a web-based :ref:`mgr-dashboard` and
-  `REST API`_.  At least two managers are normally required for high
-  availability.
-
-- **Ceph OSDs**: An Object Storage Daemon (:term:`Ceph OSD`,
-  ``ceph-osd``) stores data, handles data replication, recovery,
-  rebalancing, and provides some monitoring information to Ceph
-  Monitors and Managers by checking other Ceph OSD Daemons for a
-  heartbeat. At least three Ceph OSDs are normally required for 
-  redundancy and high availability.
-
-- **MDSs**: A :term:`Ceph Metadata Server` (MDS, ``ceph-mds``) stores metadata
-  for the :term:`Ceph File System`. Ceph Metadata Servers allow CephFS users to
-  run basic commands (like ``ls``, ``find``, etc.) without placing a burden on
-  the Ceph Storage Cluster.
-
-Ceph stores data as objects within logical storage pools. Using the
-:term:`CRUSH` algorithm, Ceph calculates which placement group (PG) should
-contain the object, and which OSD should store the placement group.  The
-CRUSH algorithm enables the Ceph Storage Cluster to scale, rebalance, and
-recover dynamically.
