DVR: Cleanup the stale snat redirect rules in router namespace
After the stale snat namespace is deleted the snat redirect rules
in router namespace should be cleaned.
Here we are basically reading the ip rule from the router namespace
and just cleaning up all the snat redirect rules leaving the default
ones untouched.

Title:
Cleanup snat redirect rules when agent restarts after stale snat
namespace is cleaned.
Status in neutron:
Fix Released
Bug description:
When the L3 agent is dead, if the gateway is removed, the snat
namespace and its rules are not properly cleaned when agent restarts.
Even though the patch https://review.openstack.org/#/c/326729/
addresses the cleanup of the snat namespace, it does not remove the
redirect rules and the gateway device from the router namespace when
gateway is disabled.
When agent restarts the agent does not get the gateway data from the
server, and so it is not possible for the agent to clean it properly.
In order to clean the snat redirect rules, the gateway data should be
cached to the local file system and reused later when necessary.
