Won't this need a version check to avoid breakage with older versions?

No, it won't need a version check. The owslib API hasn't changed.

@nyalldawson is it okay to backport this to QGIS 3.10?

Yes, but with the one release delay to avoid regressions

[tomkralidis]

FYI OWSLib 0.20.0 (with @Samweli's fix) has been released.

I just build master on Ubuntu 18.04 and got at launch (MetaSearch disabled)

from owslib.util import Authentication
ImportError: cannot import name 'Authentication'

[tomkralidis]

We need OWSLib 0.20.0 (which was release last week). How are Python 3rd party deps managed currently?
