Add network egress resource (#357)
This change adds a new import resource which enables exposing Netbird resources as Kubernetes services. This remove the need to add sidecars to every pod. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added a new `NetworkEgress` custom resource (`netbird.io/v1alpha1`) with CRD, schema validation, and status/conditions. * Extended controller functionality to create egress services and translate egress rules into import `EndpointSlice` resources; egress pods now include a kube-egress-forwarder sidecar. * **Bug Fixes** * Added missing deep-copy and declarative apply support for the new `NetworkEgress` API types. * **Documentation** * Updated README/API reference and added example manifests for `NetworkEgress` (including IP/FQDN target usage). <!-- end of auto-generated comment: release notes by coderabbit.ai --> Signed-off-by: Philip Laine <philip.laine@gmail.com>
