New features

Users no longer need to open ports 8080 and 8081 on the host for querying metrics. A new submariner-metrics-proxy DaemonSet
runs pods on gateway nodes and forwards HTTP requests for metrics services to gateway and Globalnet pods running on the nodes.
Gateway and Globalnet pods now listen on ports 32780 and 32781 instead of well-known ports 8080 and 8081 to avoid conflict with
any other services that might be using those ports. Users will continue to query existing submariner-gateway-metrics and
submariner-globalnet-metrics services to query the metrics.
Added subctl diagnose service-discovery verifications for Service Discovery objects.
The subctl join command now supports an --air-gapped option that instructs Submariner not to access any external servers for
public-ip resolution.
- Support for simulated "air-gapped" environments has been added to kind clusters.
  To use, deploy with USING=air-gap or AIR_GAPPED=true.
Support was added in the Shipyard project to easily deploy Submariner with a LoadBalancer type Service in front.
To use, simply specify the target (e.g. deploy) with USING=load-balancer or LOAD_BALANCER=true.
For kind-based deployments, MetalLB is deployed to provide the capability.
The MetalLB version can be specified using METALLB_VERSION=x.y.z.
Support was added to force running subctl verify when testing end-to-end, ignoring any local tests.
To use this feature, run make e2e using=subctl-verify.
Verifications can be now specified using the SUBCTL_VERIFICATIONS flag, instead of relying on the default behavior.
e.g.: make e2e using=subctl-verify SUBCTL_VERIFICATIONS=connectivity,service-discovery.
kubeconfig handling has been revamped to be consistent across all
subctl commands and to match kubectl’s behaviour.
- The single-context commands, cloud-prepare, deploy-broker, export,
  join, unexport and uninstall, now all support a --context argument
  to specify the kubeconfig context to use. kubeconfig files can be
  specified using either the KUBECONFIG environment variable or the
  --kubeconfig argument; kubectl defaults will be applied if
  configured. If no context is specified, the kubeconfig default context
  will be used.
- Multiple-context commands which operate on all contexts by default,
  show and gather, support a --contexts argument which can be used
  to select one or more contexts; they also support the --context argument
  to select a single context.
- Multiple-context commands which operate on specific contexts,
  benchmark and verify, support a --context argument to specify the
  originating context, and a --tocontext argument to specify the target
  context.
- diagnose operates on all accessible contexts by default, except
  diagnose firewall inter-cluster and diagnose firewall nat-traversal
  which rely on an originating context specified by --context and a
  remote context specified by --remotecontext.
- Namespace-based commands such as export will use the namespace given
  using --namespace (-n), if any, or the current namespace in the
  selected context, if there is one, rather than the default
  namespace.
- These commands also support all connection options supported by
  kubectl, so connections can be configured using command arguments
  instead of kubeconfigs.
- Existing options (--kubecontext etc.) are preserved for backwards
  compatibility, but are deprecated and will be removed in the next
  release.

Other changes

The Flannel CNI is now properly identified during join.
A new ServiceExport status condition type named Synced was added that indicates whether or not the ServiceImport
was successfully synced to the broker.
Service Discovery now handles updates to an exported service and updates/deletes the corresponding ServiceImport accordingly.
Service Discovery now returns a DNS error message in the response body when no matching records are found for the query to
clusterset.local. This prevents unnecessary retries.
Cloud cleanup for OpenStack now identifies and deletes failed MachineSets.
Privileges of the Route Agent and Gateway pods were reduced as they don’t need to access PersistentVolumeClaims and Secrets.
The privileged SCC permission for Submariner components in OCP is set now by creating separate ClusterRole and ClusterRoleBinding
resources instead of manipulating the system privileged SCC resource.
It is now possible to customize the default TCP MSS clamping value set by Submariner also for non-Globalnet deployments.
The subctl show command now correctly reports component image versions when image overrides were specified on join.
Updates to the subctl gather command:
- The subctl gather command now creates one subdirectory per cluster instead of embedding the cluster name in each file name.
- If it’s not given a custom directory, subctl gather stores all its output in a directory
  named submariner- followed by the current date and time (in UTC) in "YYYYMMDDHHmmss" format.
- The subctl gather command now includes the output from ovn-sbctl show which has the chassis-id to hostname mapping that can
  be used to verify if submariner_router is pinned to the proper Gateway node.

This is a bugfix release:

Allow broker certificate checks to be disabled for insecure connections, using subctl join --check-broker-certificate=false.
Return local cluster IP for headless services.
Display proper output message from subctl show brokers when broker is not installed on the cluster.
Allow passing DEFAULT_REPO while building subctl.
Clean up the host routes programmed by OVN RA plugin during uninstall.
Support overriding image names per-component to better support downstream builds.
Limit Azure machine name lengths to 40 characters.
Document the default cable driver in the subctl join help message.
Set DNSPolicy to ClusterFirstWithHostNet for pods that run with HostNetworking: true.
Remove hardcoded workerNodeList while querying image for GCP and RHOS cloud preparation steps.
Collect the output of ovn-sbctl show in subctl gather.
Bump x/text to address CVE-2021-38561.
Set ReadHeaderTimeout (new in Go 1.18) to mitigate potential Slowloris attacks.
