This will regenerate the Go structs used for schema validation.

## Step 4. Update the generated manifests

Tests of istioctl use the auto-generated manifests to ensure that the istioctl binary has the correct version of the charts.
To regenerate the manifests, run:

```bash
$ make copy-templates update-golden
```

## Step 5. Create a PR using outputs from Steps 1 to 4

correct sequencing of dependencies. Child manifest directories must wait for their parent directory to be fully applied,
but not their sibling manifest directories.

#### Just apply it for me

The following command generates the manifests and applies them in the correct dependency order, waiting for the
dependencies to have the needed CRDs available:

Incoming requests have multiple "layers": TLS wrapping HTTP CONNECT that is wrapping the user's connection.

To unwrap the first layer, we terminate TLS.
As part of this, we need to pick the correct certificate to serve on behalf of the destination workload.
As discussed in [HBONE](#hbone), this is based on the destination IP.
Additionally, we enforce the peer has a valid mesh identity (but do not assert _which_ identity, yet).
