Arsolitt 85fa60a33f feat(opensearch)!: issue the HTTP API certificate from cert-manager
The HTTP listener and Dashboards ran on certificates the operator minted
itself, so a client outside the cluster had no anchor it could obtain
through the platform and no way to verify the endpoint it was handed.

Issue the HTTP chain from cert-manager instead, and give the operator
the same CA through spec.security.tls.http.caSecret so it signs the
securityadmin admin certificate with it. Without that the admin
certificate would keep the operator's own CA while the listener trusted
cert-manager's, and securityadmin could no longer authenticate to apply
users, roles and audit policy.

tls.issuer names the authority rather than a switch, because the
listener serves TLS under either value and only the signer changes. It
is tri-state: an explicit value is obeyed, an absent one follows
external, because a release nobody publishes has no third party to
prove anything to. The cert-manager issuer needs OpenSearch 2.0.0 or
newer, since the operator honours the HTTP CA only from that version
and silently signs with its transport CA below it. An explicit choice
under that floor fails the render and one resolved from external falls
back to the operator, so asking for a verifiable certificate never
quietly yields less than was asked, and turning on external access
never breaks an upgrade.

BREAKING CHANGE: an externally published release on OpenSearch 2.0.0 or
newer serves the HTTP API from a cert-manager CA rather than the
operator's own. A client pinned to the operator CA must move to the
trust anchor the platform projects into the tenant.

BREAKING CHANGE: the external-dns name of an externally published
release moves from <release>.<namespace>.<cluster-domain> to
<release>.<tenant-host>, and the Dashboards name with it. This half is
gated on external alone and does not depend on the issuer. external-dns
runs upsert-only here, so the old record stays in the zone until it is
removed by hand.

BREAKING CHANGE: with dashboards enabled the application name is limited
to 41 characters, and to 32 when external access is also on. A release
above either limit now fails to render rather than converging. Such a
release was already stalled: the Dashboards Service built from its name
exceeds the 63-character DNS label limit, and the operator returns that
failure ahead of its upgrade, restart and snapshot-repository
reconcilers, so it has not upgraded or rolled since it was created. Set
dashboards.enabled to false to converge again, or recreate the
application under a shorter name.
