Add new setting for Physical Infrastructure prototype

[blomquisg]

This new setting will be used to hide/show the Physical Infrastructure top level menu. This will allow the development of the Physical Infrastructure provider to continue beyond the Fine release.

@blomquisg you don't really have to add that key, we only add the key with value as true in UI when a section needs to be visible.

@h-kataria thanks for the heads up!

I'll close this and just refer back to it for anyone that wants to know how to enable the Physical Infrastructure menu item.

Of course, set false to true in a development environment to enable the Physical Infrastructure menu item.

@h-kataria why datawarehouse_manager has an attribute set to false? I believe that, if we had physical_infrastructure it would provide an easier understanding on how to make this change in order to make the menu appear. What do you think?
