More is more - parallel extraction of app metadata

Version 1.0 was great, but lacked in terms of performance when applied to very large Qlik Sense environments.
It would take hours and hours to extract metadata for thousands of apps.

Time for version 1.1 thus.
In this version there is a new config option that lets you control how many concurrent extractions should be allowed - this pretty much cuts extraction time linearly. I.e. 5 concurrent extracts will reduce the total extraction time with a factor of 5. Nice!

Disclaimer: If you run Butler Spyglass against a small Qlik Sense server your might need to dial down the concurrency to less than 5. On a large server you can probably use a value higher than 5. You will need to test what works in your environment.
