Sync oslo network utils

A new function was added to oslo-incubator for setting tcp keepalive
settings, and dependent projects can use it.

Ran update.py in oslo-incubator to copy changed modules into nova.
Removing synced changes for jsonutils because of issues with how
strings are encoded with simplejson that cause some of our unittests
to fail.

network_utils.py (which contains the function we need, others are deps)
