Adding dependency tracking

[mattrayner]

The Problem

At @ukparliament, we'd like to track dependency calls from within our Ruby apps into Application Insights.

Suggested solution

Looking at the below documentation, there's a method called trackDependency - I'd like to implement this within ApplicationInsights-Ruby - is this currently on a roadmap, or should I just have at it?

My understanding is that we were using internal code generator to generate classes from schema. I can try to regenerate those today/tonight.

Here is a new branch with regenerated classes: https://github.com/Microsoft/ApplicationInsights-Ruby/tree/sergkanz/schemaUpdate

This branch wouldn't work now. You can use it as a starting point if you plan contribution.

CC: @yantang-msft - this update may be aligned with what you are working on. Help is appreciated!
