Pedro Almeida 25f9cc35db Update cert-manager version to v1 from v1alpha2
Following the cert-manager migration to FluxCD, it was upversioned to
v1.7.1 from v0.41.2, which means we need to update our helm-chart
docs to use v1 instead of v1alpha2.

Closes-Bug: #1978858

=========================================================================
Configure REST API Applications and Web Administration Server certificate
=========================================================================
.. rubric:: |context|
|prod| provides support for secure HTTPS external connections used for
StarlingX REST API application endpoints (Keystone, Barbican and StarlingX) and
the |prod| web administration server. By default, HTTPS access to StarlingX
REST and Web Server endpoints is disabled. They are accessible via HTTP only.
To enable secure HTTPS access, an x509 certificate and key must be configured.
You can update the certificate used for HTTPS access at any time.
To configure or update the HTTPS certificate for the StarlingX REST API and Web
Server endpoints, create a certificate named ``system-restapi-gui-certificate``
in the ``deployment`` namespace. The ``secretName`` attribute of this
certificate's spec must also be named ``system-restapi-gui-certificate``.
See the example procedure below for creating the certificate for the StarlingX
REST API and Web Server endpoints. This example assumes you have configured a
``system-local-ca`` ClusterIssuer as described in
:ref:`starlingx-rest-api-applications-and-the-web-admin-server-cert-9196c5794834`.
Update the following fields:
* The ``duration`` and ``renewBefore`` dates for the expiry and renewal times
you desire. The system will automatically renew and re-install the
certificate.
* The ``subject`` fields to identify your particular system.
* The ``ipAddresses`` with the |OAM| Floating IP Address for this system.
* The ``dnsNames`` with any |FQDN| names configured for this system in an
external DNS server.
.. note::
If you plan to use the container-based remote CLIs, due to a limitation in
the Python2 SSL certificate validation, the certificate used for the
'system-restapi-gui-certificate' certificate must either have:
1. CN=IPADDRESS and SANs=IPADDRESS
or
1. CN=FQDN and SANs=FQDN
where IPADDRESS and FQDN are for the |OAM| Floating IP Address.

#. Verify the configuration.
.. code-block::
~(keystone_admin)]$ kubectl get certificate system-restapi-gui-certificate n deployment
If configuration was successful, the certificates Ready status will be
``True``.
.. rubric:: |result|
The REST and Web Server certificate installation is now complete, and
Cert-Manager will handle the lifecycle management of the certificate.
