update identity to handle new table attributes

create_tenant JSON client currently passes 'enabled' as a string.
'enabled' should be passed in as bool.

new table attributes returns 'description' and 'enabled' values in the
body of response instead of in 'extras'. update test_tenants to check
the new location
