Add CMF plugin on Che

[19yak]

@svor, @DKuleshov, @vzhukovskii and @dimasnurenko

I need documentation that explains the different steps for the addition of this plug-in Che.
My Che version is 5.0.0

Khaled - as that is very old code, that is going to be code that is something you will need to investigate in your own.

Sorry we do not have long tutorials on these items - we will be preparing more materials about working with modeling later this year.

In the mean time the eclipse source article and our docs and our code base is what we can share.
