Data Analysis RPC server over Tango

Dahu is a lightweight plugin based framework...
... technically a JSON-RPC server over Tango

* plugin can be class or can be generated from state-less function
* a plugin is executed within a job, each job lives in its own thread.
* plugins have empty constructors plus 4 methods (or more)
- setup allows to set the input parameters. It performs sanitization if needed
- process does the taff
- teardown sets the output and the logging and cleans up if needed
- abort can be used to stop the processing if a plugin is a daemon.
* the job is responsible for serializing on disk the plugin input and output
* jobs can be launched using the tango interface (or other ...)
* plugins have a single input and output, they are simple JSON-serializable dictionaries.
