Add basic documentation for multibucket object store

Browse Source 
This configuration sample quite sadly was lost during some
reorganisation in the past. It’s quite useful to be kept in the main
documentation.

It's possible to configure Nextcloud to distribute the data over multiple buckets
for scalability purposes.
To setup multiple buckets, use :code:`'objectstore_multibucket'` storage backend
in :code:`config.php`:
::
'objectstore_multibucket' => [
'class' => 'Object\\Storage\\Backend\\Class',
'arguments' => [
// optional, defaults to 64
'num_buckets' => 64,
// will be postfixed by an integer in the range from 0 to (num_nuckets-1)
'bucket' => 'nextcloud_',
...
],
],
Multibucket object store backend maps every user to a range of buckets and saves
all files for that user in their corresponding bucket.
.. note:: While it is possible to change the number of buckets used by an existing Nextcloud
instance, the user-to-buckets mapping is only created once, so only newly created
users will be mapped to the updated range of buckets.
You can find out more information about upscaling with object storage and Nextcloud in the
`Nextcloud customer portal <https://portal.nextcloud.com/article/object-store-as-primary-storage-16.html>`_.
