Description

From https://github.com/GoogleContainerTools/skaffold/pull/3732#issuecomment-595403953

We should support kubectl-style nested config values for setting the global config, e.g.

kubectl config set-cluster e2e --server=https://1.2.3.4 and kubectl config set clusters.e2e.server https://1.2.3.4

Research direction
Review the linked PR #3732 and the current global config implementation in `pkg/skaffold/config/`. Look at how kubectl handles nested config values (e.g., `kubectl config set clusters.e2e.server`). Propose a similar approach for skaffold's global config, possibly using a similar dot notation or subcommand pattern. Check if there are any existing tests or discussions in the comments.
