Basically, Gargantext.Prelude exports all of Protolude now.

This important commit introduces the 'DbCmd' constraint set, allowing DB
functions to require only a connection pool and some `GargConfig`.

This reverts commit b7e406b1.

First add New type NodeFrameVisio it this case:
	modified :         src/Gargantext/Database/Admin/Types/Node.hs
After this step, just follow the compiler errors to fix the instances.

	modified :         src/Gargantext/Prelude/Config.hs

The NodeType NodeFrameVisio is created in Database and need some
parameters:
	modified :         src/Gargantext/Database/Action/Node.hs
	modified :         src/Gargantext/Database/Admin/Config.hs
	modified :         src/Gargantext/Database/Admin/Types/Hyperdata/Default.hs

Finally:
	modified :         gargantext.ini_toModify
The url of the micro-service can be adapted in gargantext.ini

This turned out to be quite heavy because of module import cycles.
