[QGIS-Developer] setting user-agent from QgsNetworkAccessManager or QNetworkRequest

[Marco Lechner - FOSSGIS e.V.]

Hi,

in QGIS one can set the user-agent to a cutom value in the program 
options, but QgsNetworkAccessManager automatically adds "QGIS/.../.. " 
to the user-agent string.
Is there a way to completely set a custom user-agent string (without the 
QGIS addition?). How can I set the user-agent on QGIS plugin development 
when using QgsNetworkAccessManager with QNetworkRequest? 
QgsNetworkAccessManager seems to take care of the sytsem configuration. 
And therefore QGIS... is added there as well. How can this be changed? I 
do not want to use "requests" instead of QgsNetworkAccessManager.
