ZF2 Module Installer

gistfile1.txt

I want the ability to be able to "install" modules which require installing. 
If they have not been installed, then they should not be loaded.

Imagine there is one module in a ZF2 Skeleton App. Named "Hub". 
It has an "install" cli route, which loops through all loaded modules. 
If they implement "InstallableInterface" they will provide some install service. 
The "install" command will run each of these
services "install" method.

One example (my use case) is that I need to loop thorugh each user and create a 'user_flex_settings' row for them. 
This row is only required when the module "JhFlexiTime" is loaded.

If the install command has not been run, I want to disable loading those modules which have not been installed yet. 

The modules are recorded as installed using a module_status table, so after installing a module, 
a row should be inserted 
into that table.
