Bug Description

This relates to https://bugs.launchpad.net/neutron/+bug/1052535. The problem with deleting namespaces was found to be caused by the iproute package. See that bug for details.

For those deployments on newer distros with the iproute fix, it should be possible to enable automatic deletion of namespaces. However, this capability should be configurable and turned off by default in order to not adversely affect deployments with broken iproute package.

    Optionally delete namespaces when they are no longer needed

    Adds a configuration option to tell the network agents to delete
    namespaces when they are no longer in use. The option defaults to
    False so that the agent will not attempt to delete namespaces in
    environments where this is not safe.

    This has been working well in deployments where iproute2 has been
    patched with commit 58a3e8270fe72f8ed92687d3a3132c2a708582dd or it is
    new enough to include it without being patched.
