Aleksei Sviridkin 2b25163a8f refactor(sdn)!: reshape SecurityGroup into a membership-group model ...

Give each SecurityGroup its own membership label
(securitygroup.sdn.cozystack.io/<name>) and select it from the backing
CiliumNetworkPolicy, instead of deriving the endpointSelector from a single
app's lineage labels. spec.targetRef becomes spec.attachments, so one
SecurityGroup can apply to several applications at once.

Peers move from free-form fromEndpoints/toEndpoints selectors to
fromApp/toApp (resolved to lineage labels) and fromSG/toSG (resolved to
another group's membership label, a reference the Cilium dataplane resolves
live). Attachments are persisted in a storage-owned CiliumNetworkPolicy
annotation, round-tripped and hidden from the SecurityGroup view like the
marker label. Validation now covers attachments and app/SG peers and rejects
names that collide with reserved Cilium entities.

The membership labels are maintained by a separate controller added in a
follow-up commit; this change covers the API types and the
aggregated-apiserver projection only.

BREAKING CHANGE: SecurityGroup spec.targetRef is replaced by
spec.attachments, and ingress/egress peers use fromApp/fromSG/toApp/toSG
instead of fromEndpoints/toEndpoints. The feature is unreleased, so no
migration is required.
