Update complete workshop version to have Phobos working

[IgorFedchenko]

When checking out to master branch, there are few things that have to be fixed before the solution is working properly.

In this PR, I am going to fix things step by step to make cluster working and Phobos collecting traces and metrics.

[IgorFedchenko]

I was working on fixes in master branch - now making PR to dev, so will need to make sure all fixes still apply to development branch.

@IgorFedchenko we will probably need to update all of the lesson-specific branches too 😬

[Aaronontheweb]

but let's get this branch working first

we will probably need to update all of the lesson-specific branches too 😬

Oh yeah, looks like I will need to know this workshop even closer :)

[IgorFedchenko]

Ok, now Phobos services are starting fine, but still seem to not be reporting to Jeager.

[Aaronontheweb]

any idea why the build is failing?

[IgorFedchenko]

It was not compiling outside of Phobos build configuration. Fixed that.

[IgorFedchenko]

Need also migrate metrics reporting from statsd to Prometheus, since statsd is not supported right now directly by App.Metrics.

@IgorFedchenko do you intend to go ahead and finish this PR? I really would love so ... and @Aaronontheweb can we boost this project to be more update?

[IgorFedchenko]

@Caldas Eh, I think this PR will take more efforts to complete then I can give it right now. So if you want to continue my work - go ahead and pick it up (check out my working branch and create new PR with your changes based on mine).
