replace node_exporter https package with exporter-toolkit

The node_exporter/https package has been moved to exporter-toolkit as of
v1.1.0. weaveworks/common was still using this package, which was
preventing downstream importers (i.e., grafana/agent) from updating
their dependency on node_exporter.

This change also required bumping kuberesolver to v2.4.0 (the next
version after v2.1.0) which uses a newer version of the gRPC library
where type names have changed.
