[Development] Coin production update

[Aapo Keskimölö]

Hi Qt Developers,


The process for reporting CI issues has been changed: 
https://wiki.qt.io/Reporting_Bugs#Reporting_bugs_for_CI


Coin has been awarded with its own JIRA project and therefore, new 
issues should be reported under project COIN. The old Coin component in 
QTQAINFRA will be marked as deprecated.


Other infrastructure related issues (provisioning, opennebula, network, 
etc.) can still be filed under the good ol' QTQAINFRA project.


Best of luck,

Aapo
