    Remove deprecated use_namespaces option

    The use_namespaces option has been defined as a workaround to kernels
    not properly supporting namespaces. This limitation is behind us, it's
    time to remove use_namespaces after its deprecation in Kilo in order to
    simplify code and remove a poorly tested case (use_namespaces=False).

    This change prepares for removal pullup_route method[1] which was only
    used when use_namespaces=False.

The options is documented in various places like:

doc/networking-guide/source/scenario_dvr_ovs.rst
doc/admin-guide-cloud/source/networking_multi-dhcp-agents.rst
...

We need to update all of them

Reopening bug due to incomplete patch. In the networking guide, the 'use_namespaces' option exists in scenarios besides DVR.

[Tyler Britten (9-me-9)]

Just saw that. Will review and correct the additional instances.
