Complex products children ids are not cached in Type class leading to multiple unnecessary db requests

[PierreLeMaguer]

Description

in the product page, the method 'getChildrenIds' is called several times and each time we make an SQL request to get this info.
For example juno-jacket.html with the sample data, the method of the configurable type is called 20 times.

The problem
The result of this method is not stored in a cache to avoid to make useless request.

benefits
We earn time by making a cache and storing the results instead of making SQL requests.
