Add kstat-based Solaris metrics (#1197)
* collector/loadavg_solaris.go: Use libkstat to gather load averages. * go.mod: Added go-kstat. * boot_time_solaris.go: Added. * cpu_solaris.go: Added. * README.md: Updated entries for Solaris. * collector/zfs_solaris.go: Added. * CHANGELOG.md: Added note about kstat-based Solaris metrics.
