• Add -i parameter to more tools (addresses #243)

202010 release

Change log:

• support select metrics in virtual machines with vPMU support (e.g. AWS virtualized instances with arch_perfmon flag). Screenshot of grafana dashboard with PCM data from a c5.9xlarge virtualized AWS instance
• pcm-iio: fix VT-d events on SKX

202009 Release

Change log:

• pcm-memory: make -pmm/-pmem the default option on systems with PMM/PMem support
• pcm-tsx: update events for ICL and SKL, allow collection of up to 8 events
• pcm-raw: support fixed PMU counters
