Importing a model caches all moose groups

[LABSARI]

See the method MooseModel>>cachesMooseGroups.
It should cache only most useful groups, not all.

[NicolasAnquetil]

most useful groups could be ModelClasses, ModelMethods, ModelPackages
or we remove all caching ?

When working on a playground, I always use
installWithCache: false

Because I consider that caches will be filled when needed.
For the UI, what's interesting is that people will be able to use the UI faster (after loading the model, no more wait time)

I suppose that Classes and packages are great :-)
Not sure for methods, when having a big model, I expect someone to first search for the class, and then for its methods

[LABSARI]

So we can set installWithCache: with false for now.
