Performance regression in azure inventory (starting in 3.9.0)

[Klaas-]

SUMMARY

It seems that there is a big performance hit in azure inventory starting with version v3.9.0

Same subscription, same configuration:

3.12.0 11m6.853s
3.11.0 9m59.946s
3.10.1 10m41.090s
3.9.0 9m4.123s
3.8.0 3m37.551s

v3.8.0...v3.9.0

only change for inventory seems to be
#2055

I think this looks like the added calls are not being made via the batch API? I'll look if I can fix that :)
