Updating Associations::Preloader docs

Much of the previous documentation introduced features new in 2011. This

time describing the normal case (preloaded associations) and less time
describing the fallback.

get rid of shadowing warning when running tests AR and railtie tests.

Warning looked like this:

```
/Users/senny/Projects/rails/activerecord/lib/active_record/associations/association_scope.rb:142: warning: shadowing outer local variable - reflection
```
build fix, we have to reset the RACK_ENV as well.

This is a follow-up to ded17a4 to get the build passing on Travis.
As Travis has `ENV["RACK_ENV"]` set to `test` we need to reset that as well.
Enums shouldn't ruin people's anniversaries

Added a few more methods on Module/Class to the dangerous class methods
blacklist. (Technically, allocate and new are already protected currently because
we happen to redefine them in the current implantation.)

Skip StatementCache for eager loaded associations (Fixes #16761)

Eagerly loaded collection and singular associations are ignored by the StatementCache, which causes errors when the queries they generate reference columns that were not eagerly loaded.

This commit skips the creation of the StatementCache as a fix for these scenarios.
Remove example file

Passing a `:usec` that's out of range now throws an `ArgumentError` as it
should.

Fixes #16759.
