drop support for passing VirtualColumn and Reflection objects

no app code ever passes virtual column or reflection objects to the
add_* methods, so we don't need to support that case.
Specs use case insensitive fqname for comparison

Automation engine uses lowercase names for domains, namespaces
class, instances and methods. It can be refered to in mix case in
the models. The fqname is critcal to locating files in the new
git based automated model, by having mixed case the search takes
longer so we are planning on using all lowercase name when storing
files in git and the fqname becomes all lowercase.
Add ClassCheck preference and disable StringLiteralsInInterpolation cops

Remove "initialize" method from StorageManager model.

The initialize method of the StorageManager model class was calling super()
and in so doing, not passing the proper args to the subclass. Given
this was all the method did, the entire method has been removed.
