Use retry logic when `kapp deploy` encounters `client connection lost`

`kapp deploy` fails without retry on `http2: client connection lost`

Example from our CI environment which uses kapp deploy:

3:46:49PM: Deploy failed

| kapp: Error: waiting on reconcile packageinstall/bitnami-services (packaging.carvel.dev/v1alpha1) namespace: tap-install:
| Errored:
| Getting resource packageinstall/bitnami-services (packaging.carvel.dev/v1alpha1) namespace: tap-install:
| API server says: unexpected error when reading response body. Please retry. Original error: http2: client connection lost (reason: )
