[WIP] Regenerate for 1.30, fix patches

[brendandburns]

@yue9944882 I regenerated for 1.30 including the fixes for nullable arrays, also fixed up the patches so they applied cleanly.

Ref #3076

Please take a look.

Tests are failing b/c the YAML is being generated with empty lists intead of nulls, I'm not sure this is easily fixable but will investigate.

YAML is fixed, but one JSON test is failing and needs a fix.

Ok, I updated this so that empty lists are omitted from YAML dumping and I think that should be ok.

Error:    KubectlDeleteTest.kubectlDelete:216 No requests exactly matched. Most similar request was:  expected:<
DELETE
/apis/batch%2Fv1/batch%2Fv1/namespaces/foo/jobs/bar

[equalToJson]
{
  "propagationPolicy" : "Foreground"
}> but was:<
DELETE
/apis/batch%2Fv1/batch%2Fv1/namespaces/foo/jobs/bar


{
  "dryRun" : [ ],
  "propagationPolicy" : "Foreground"
}>

it looks like k/k api added a new dry-run option for delete API, so we need to align with that. i will append another commit to fix it
