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

[Sam Coward]

Describe the problem/challenge you have
kapp deploy fails without retry on http2: client connection lost

Example from our CI environment which uses kapp deploy:

	    | 3:45:49PM: ---- waiting on 6 changes [61/67 done] ----
3:46:49PM: Deploy failed 
	    | E0607 15:46:48.669366      32 request.go:1058] Unexpected error when reading response body: http2: client connection lost
	    | 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: )
	    | Deploying: Error (see .status.usefulErrorMessage for details)

Describe the solution you'd like
Use retry logic when this sort of network error is encountered.

Anything else you would like to add:

We do have a set of errors we retry for, this would qualify as an addition if we are sure that we won't risk retrying in cases which we cannot recover from while matching to this error string
