Subject: [PATCH] Change the directResponse.body.bytes format to `byte`

According to our documentation, base64-encoded values should be used in
this field, in which case `byte` is the correct format rather than
`binary`.

+    **Fixed** warning when installing VirtualService CRD due to 'unrecognized format "binary"' by switching to `format: byte` for the field `spec.http.directResponse.body.bytes`. This does not impact user experience, as input is still expected in base64-encoded form as is already documented.
