configure_kerberos usage and using

[cbaenziger]

Need to use configure_kerberos in wrapper recipes:

For example, the code in smoke_test_wrapper could much better use configure_kerberos.

IIRC configure_kerberos can't handle non-host keytabs or something. Needs to be refactored to be able to generate "user keytabs"

Here's a useful extended grep for finding all of the references to the keytab dir attribute in the cookbooks: egrep -irn "\[[:'\"]?keytab['\"]?\]\[[:'\"]?dir['\"]?\]" cookbooks/

It seems what got my attention with smoke_test_wrapper is that I was accidentally running with kerberos disabled for reference. Thanks for the heads-up @aespinosa.
