[wildfly-dev] question 2 sec boot time of WISE

[Darran Lofthouse]

Once a subsystem is adding it's own web app programatcially does make me 
think we can't be far off being able to dynamically register it on the 
HTTP management interface (Standalone Mode), so rather than updating the 
configuration model for the management interface the additional context 
is defined in the subsystem that added it.
