1. Check for nullptr if metadata is set. 2. Changing scaling_factor to be multiplied instead of divided (dcdb nomenclature).

Removing puning of ints to doubles and viceversa, and implementing use of scaling factor from metadata

SMUCNGPerf Operator: implementing memory bandwidth. PerSystSql Operator: fixing issue with one unit not being present, and no calculation was done.

- Now using references instead of pointers
- Return type is now bool

- Make clean might be required

- The "observations" operation simply counts the number of total queried
elements over the inputs of each unit

- An OpenCV-based regression plugin using Random Forest models
- Also added a few missing copy constructors

- Compiles fine but completely untested for the moment
- Also addressed many bugs for job analyzer templates

- Now supports also standard deviation and percentile computation
- Multiple output sensors per analyzer can be defined, each performing
a different aggregation task
- QueryEngine has been slightly modified so as not to clear the input
sensor reading buffer (if any), thus allowing to accumulate sensor
values with subsequent calls
