Add azure blob support

[prestist]

Separated commits because of the extreme of vendoring.

Still needs to be tested, working through that atm.

[prestist]

I have tested this and it does work! yay;

Alright; outstanding things;

Obviously need to rebase and fix conflicts ✅

Need to add documentation, and I started here on this documentation; was thinking about examples.md but after thinking about it I dont think that makes any sense, there is no sig change and it would work from the point of remote-ign files.

Was thinking about breaking out the parse logic for url into a func just for unit testing but wdyt?

One question but looks good. The main thing we'll have to look at is if the licenses of the introduced code are compatible with our own.

[prestist]

@travier re the licensing I think we are g2g since we are set as Apache v2.0

Both seem to be MIT =>
microsoft-authentication-library-for-go
azure-sdk-for-go
