mgr/dashboard: add patch that removes PyOpenSSL-related usages

This patch allows the dashboard to work again with TLS enabled; it
however disables the possibility to create self-signed certs via the
`ceph` CLI. This means that users will have to supply the correct
key/cert pair themselves, which are just a few extra steps instead. [0]

Users that try to generate a self-signed cert via the `ceph` CLI are
instead provided with instructions on how to generate and configure a
key/cert pair themselves.

Additionally, the check whether the cert and key match is removed during
the dashboard's launch.

See the patch for additional details.

Subject: [PATCH] mgr/dashboard: remove ability to create and check TLS
key/cert pairs
In order to avoid running into PyO3-related issues [0] with PyOpenSSL,
the ability to create self-signed certs is disabled - the command
`ceph dashboard create-self-signed-cert` is made to always return an
error.
The command's error message contains the manual steps the user may
follow in order to set the certificate themselves, as well as a link
to the Ceph Dashboard documentation regarding TLS support. [1]
Furthermore, the check on start-up, that verifies that the configured
key/cert pair actually match, is also removed. This means that users
need to ensure themselves that the correct pair is supplied -
otherwise their browser will complain.
These changes allow the dashboard to launch with TLS enabled again.
