Allow more configuration with Catalog.validate_all

[jsignell]

Replaces #1141

Related Issue(s):

• Closes Allow more configuration with validate_all #345

Description:

I think this covers the scenario described in the original issue of limiting the amount of objects that are iterated over. It made more sense to be to track that as a single number (items + catalogs + collections) and then to separately give a knob for changing whether or no we recurse into the children.

That being said there are lots of ways to tackle this. Anther approach could use a timeout rather than tracking number of objects at all.
