Liferay provides site administrators the ability to create custom Web Content Templates to customize the display of web content articles with specific Web Content structures. However in some contexts it's not desired to enable this possibility since it provides too much power and possibilities of impacting the system through bad template code. For sensitive systems, it might be preferable to disable Web content Templates and reduce the customizability in exchange for higher system safety.
The goal of this story is to provide a configuration option, which allows System Administrators to completely disable creation of new Web Content Templates for the whole system (all of its virtual instances). When Web Content Templates are disabled, it should not be possible to create new Web Content templates through any UI or API.
