fix the version set in description of a new node js repo
Do not return a unclear error message if json_data is not set

Test with :
   curl -d ''  http://127.0.0.1:8080/broker/cartlist

While this should return a error message, the current code return
a ruby traceback, which is not helpful to understand what is going on.
changed mirror1.stg and prod to mirror1.ops
oo-accept-broker: drop sysctl checks

In oo-accept-broker, we have the check_kernel_settings function which
checks some sysctl settings.  However, we only change these settings on
the node, so these checks do not belong in oo-accept-broker.

The invocation of check_kernel_settings is commented out, so the checks
were never run.  This commit deletes both the commented-out invocation
and the definition of check_kernel_settings.
use awk instead of awk, cat and grep. Just for having more compact code
