Rafactoring of fuel-stats analytic module
Rafactoring of fuel-stats analytic module

The section '#to be removed' replaced by 'ensure_packages' section.

The 'fuel-stats' application is working fine with default configuration
of the 'elasticsearch' package, therefore we can remove
the definition of elasticsearch class from the module.
