- Now all sensors across all plugins adopt the naming convention
cpu<CPUid>.<sensorName>, if CPU-related, or just <sensorname> otherwise
- Code to parse cpu sets used both in Perfevent and ProcFS plugins
moved up in ConfiguratorTemplate
- Misc code to format MQTT parts also moved up in ConfiguratorTemplate

- This commit reflects changes made in the master branch and should
make the eventual merge less painful

- Added logic to compute a MemUsed metric, which corresponds to
(MemTotal - MemFree) for meminfo files
- To use this feature, a sensor of type MemUsed must be explicitly
defined in a meminfo sensor group in the procfs config file

- Parser and sensor group objects do not share the same sensor objects
anymore
- Sensor values are stored in the respective objects by the sensor
group itself, like in the other plugins

- Added a ProcstatPercParser: similar to ProcstatParser, for each CPU-related line it will collect for each column the percentage of the related value with respect to the sum of all columns, instead of raw values
- Can be selected by specifying sensor groups of type "procstat_perc"

- Reflects changes applied in the master branch

- Switch from the STD regex library (which apparently is incomplete for GCC < 4.9) to the BOOST one
- Plugin is stable and tested on a CoolMUC3 node
- Current overhead for a full vmstat + meminfo + procstat instantiation is 1.3% on a CoolMUC 3 node with 256 (logical) cores
- More optimization work to come

- Supports sampling of the vmstat, meminfo, and stat files in the proc virtual filesystem
- Basic functionality verified, extensive testing to come in the next days
- Readme and Makefile have been updated as well
