Get closure on DWH front

[rlaemmel]

• Host mySqlOneReporting in your github area.
• You could use 1 repo or 2 for the two contributions.
• Please edit 101repo/.gitdeps to link to pyDWH and mySqlOneReporting.
• Remove mySqlOneExtended from 101repo.
• Add Feature:Dimensionality
• Probably retire several features Gender, Age, Job_role, .. that feed into Feature:Dimensionality
• Check and remove Feature:Grouping which is probably an early version of Feature:Dimensionality.
• Add Feature:Conversion
• Demo Feature:Dimensionality with Contribution:pyDWH.
• Remove all traces of "average".
• Decide on whether Feature:Dimensionality can / should be demonstrated with mySqlOneReporting.
• Please think deeply whether any of the data extensions of Feature:Dimensionality can be eliminated so that it is easier for others to reproduce the feature consistently.

Hi Ralf,

"Please think deeply whether any of the data extensions of Feature:Dimensionality can be eliminated so that it is easier for others to reproduce the feature consistently."
--> "Gender" could be eliminated since it is similar to "Age" whereas "Age" is more complex and more interesting due to the use of ranges.
