update chef-pedant to 1.0.60
Correct to erchef standard
Added option to disable license endpoint tests for Chef 11 (and earlier?)
No longer pivot on ruby_org_assoc as returns are consistent
Change license_endpoint? to chef_12? for more generic API behavior diffs
Pend header spec until backport from cs12
Set dep for test
Change list vs. string error behavior to match Chef 12 behavior
