[CT-282] Implement better way of handling target attributes for deps and clean commands

[gshank]

In ticket #4752 and pull request #4758 we implemented a quick fix for customers with references to target attributes in the jinja of their config files. We also have an issue with a poor error message for cases where users have typos in the target attributes. We should look at better ways of handling these two things, possibly by limiting config reading or a more-full-fledged no-profile target class. If an attribute does not exist, we should throw a reasonable error message.
