Add new sysfeatures module as experimental (RRZE-HPC#581)

* First iteration of new hwfeatures module, mainly for Intel systems

* Finish Intel RAPL feature

* Update hwfeatures with AMD RAPL

* Limit string length in hwFeatures

* Rename hwfeatures to sysfeatures as it contains more than just hardware features

* Rename sysfeatures variables, move likwid_device types, exclude code when not configured, add meta info

* Fix sysfeatures test and add make target

* Delete empty sysFeature for transparent hugepages

* Fix merge error
