[bugfix] Enable WFS-T for 2.0.0 and 1.1.0 Fixes #15597

[elpaso]

Tested on GeoServer and QGIS Server

Needs forward port to master

Huh is that all what is needed for WFS-T 1.1 and 2.0 ? Just a small update when parsing capabilities ?

Ah, I see: you must still do WFS-T 1.0 for the Transaction operation. In which case this is not really WFS-T 1.1 and 2.0. The commit message should reflect that since that means that a server that would just implement WFS-T 1.1 or 2.0 wouldn't work.

Yes, the transactional part is still 1.0. I'll amend the commit message. BTW the default version "auto" will now work with most of GeoServer installations without the need to manually set 1.0.

Didn't you experience issues when doing the Transaction part in WFS-T 1.0 and thus getting 'fid' attributes when creating a feature, and the GetFeature part in WFS 1.1/2.0 getting a 'gml:id'. fid are typically just numerical values whereas gml:id is generally feature_type_name.serial_number. That could lead to duplicated features.

I'm not yet at it and I'm now adding tests for WFS-T 2.0.0, I realize that this is only a partial fix.
Are the duplicated features generated on insert only or also on update?

@rouault It seems that the WFS-T with GeoServer has severe issues in current 2.18 and master even if I manually set 1.0.0, see here: http://hub.qgis.org/issues/16043#note-5
