Remove Azure Exporters out of main repo (master)

[lzchen]

Addresses [#193].
Remove Azure exporters out of OpenTelemetry repos.

I've published a new Pypi package called opentelemetry-azure-monitor-exporter which is in a separate repository. You can see it here.

@c24t I think we should deprecate the already existing package and link it to the new one.

@victoraugustolls FYI

It would be good to add some reference to Azure repo in OpenTelemetry python readme or somewhere else so people are aware it exist, is there any plan for this?

[c24t]

Edit: the new repo is here: https://github.com/microsoft/opentelemetry-exporters-python.

@lzchen why not continue to use the opentelemetry-ext-azure-monitor name?

@c24t
For Microsoft, we've been using the term integrations instead of extensions. I am not that good at naming but I did not want to include anymore new terminology to our package names. opentelemetry-azure-monitor-exporter is very obvious at what it is for.

I did not want to include anymore new terminology to our package names

That makes sense, but now we've got two naming conventions. I opened #283 to track this.

FYI technically you've relicensed that code from Apache2 to MIT, which generally isn't permitted without explicit permission from the code author.

I figure no one here is going to sue, but In the future we may want to consider license ramifications before moving code places.

@toumorokoshi
That is a good point. We've gone through the necessary legal resources to address this issue. As well, the code we are taking was written solely by @reyang so we shouldn't have any legal ramifications.
