- Added a 'common' directory where all shared code has been placed
- Analytics package has been moved out of dcdbpusher, now has its own makefile
- Some renaming here and there for uniformity

Bump mosquitto to version 1.5.5, add patch to replace select() call by poll() to solve issues with sockets > 1024

- Small fixes to prevent compilation warnings

- Auto-publish has been split in two parts: construction of the
sensor names is performed within the Configurators, whereas the MQTT
messages are sent from the MQTTPusher
- This way, sensors always have the correct names upon plugin reloads
- Will make switching to textual MQTT topics easier

- First working version of Data Analytics Framework
- A test plugin that performs the sum and max of its input sensors was
implemented

- Allows to instantiate an arbitrary number of sensors which output
incremental values
- Naming and MQTT topic selection are performed automatically
- Useful to stress test the collectagent and verify overall performance

Separating the installation of configuration files from binaries/libs, otherwise they get overwritten with make install

- dcdbpusher can now be configured to automatically publish its
sensors by communicating the MQTT topic -> name mapping to the
collectagent through appropriate messages
- See the README for further details
- As of now, dcdbpusher performs auto-publish (when required to) and
then proceeds with normal operation; this should be changed so that
the pusher terminates gracefully after having published the sensors

- 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

This is the first batch of changes, more to come
