* chore!: adopt log/slog, drop go-kit/log Requires: prometheus/common#697 This PR includes: - linter updates to enable `sloglint` linter - Go dep updates for prometheus/{client_golang,common,exporter-toolkit} libs - refactorings to adopt log/slog in favor of go-kit/log The bulk of this PR was automated by the following script which is being used to aid in converting the various exporters/projects to use slog: https://gist.github.com/tjhop/49f96fb7ebbe55b12deee0b0312d8434 Builds and passes tests locally with go workspaces and up-to-date main branch of prometheus/common. Signed-off-by: TJ Hoplock <t.hoplock@gmail.com> * build(deps): bump prometheus/common to v0.60.0 Signed-off-by: TJ Hoplock <t.hoplock@gmail.com> --------- Signed-off-by: TJ Hoplock <t.hoplock@gmail.com>
