First commit
Added files for loading old mon data in sql and evaluating the elasticity (used in cloud come xtended experiments)
Added feature in which now wwhen MELA starts it starts with an initial DEMO configuration.
Moded data pooling from AnalysysService to MELA-DataService.  Also, AnalysysService can be run as shaded jar.
Separate data pooling from Analysys to DataService, and removed state from analysis service.
Last configuration now stored as XML in database. ALso, hsitorical monitoring data is accessible between runs.
Added services which return elasticity space and pathway also in XML, to be processed if needed from external tools.
Refactored data source to create a base for multiple data source definitions. Also, inserted base for supporting push and poll data collection mechanisms at different pooling intervals.
Added Data Sources separate configuration to support multiple data source pulled at diff intervals. Basis for also push provided. Currently all data soruces link to same Service. Will separate to manage more services.
Added files not commited in previous version.
Updated structure auto detection to work with multiple data sources.
Update dataSources.conf
Added Raw data SQL persistance, and method for retrieving available monitored metrics per MonitoredElement
Added elasticity space caching usind database.
Merge branch 'master' of https://github.com/tuwiendsg/MELA
Reduced disk storage footprint for elasticity space cache. Added service for retrieving monitoring data for specific element.
Moved elasticity space caching to AnalysisService where it will be done on demand, thus decreasing the load on the MELA-DataService DataCollectorService
Removed bug in which historical elasticity space was reported incorrectly.
In case composition operation fails, the value is not returned anymore, instead of returning -1. This reduces data polution.
Updated neuron.
