[BUG] Custom proxy with error "Expecting a valid host string in proxy settings, but found" about applicationinsights-node.js HOT 1 CLOSED

@hintdesk This looks to be related to Node.js's URL class and how it parses URLs. ApplicationInsights 3.X SDK relies on the Azure SDK's core-rest-pipeline, which in turn parses the proxy URL here. While this works fine for the string http://proxy.companyname.i, the method fails on proxy.companyname.i (which is what the method receives there as it's given the proxy's host string instead of the full URL). I'll file an issue on the core-rest-pipeline side as it seems like this issue would affect anyone attempting to pass in valid proxy URLs with multiple . characters.
