pkg: kubelet: remote: increase grpc client default size
Signed-off-by: Antonio Murdaca <runcom@redhat.com>
**What this PR does / why we need it**:
when running lots and lots of containers and having tons of images on a given node, we started seeing this in the logs (with docker):
```
Unable to retrieve pods: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (4208374 vs. 4194304)
```
That's because the grpc client is defaulting to a 4MB response size.
This patch increases the resp size to 8MB to avoid such issue.
