When running in a user namespace created by an unprivileged user the
owner of /var/run will be reported as the unknown user (as defined in
/proc/sys/kernel/overflowuid) so any access to the directory will
fail.
If the XDG_RUNTIME_DIR environment variable is set, check whether the
current user is also the owner of /var/run. If the owner is different
than the current user, use the $XDG_RUNTIME_DIR/netns directory.

The CNI spec states that for DEL implementations, "when CNI_NETNS and/or
prevResult are not provided, the plugin should clean up as many resources as
possible (e.g. releasing IPAM allocations) and return a successful response".
This change results in the firewall plugin conforming to the spec by not
returning an error whenever the del method is not provided a prevResult.

Previously, if an IPAM plugin provided DNS settings in the result to the PTP
plugin, those settings were always lost because the PTP plugin would always
provide its own DNS settings in the result even if the PTP plugin was not
configured with any DNS settings.
This was especially problematic when trying to use, for example, the host-local
IPAM plugin's support for retrieving DNS settings from a resolv.conf file on
the host. Before this change, those DNS settings were always lost when using the
PTP plugin and couldn't be specified as part of PTP instead because PTP does not
support parsing a resolv.conf file.
This change checks to see if any fields were actually set in the PTP plugin's
DNS settings and only overrides any previous DNS results from an IPAM plugin in
the case that settings actually were provided to PTP. In the case where no
DNS settings are provided to PTP, the DNS results of the IPAM plugin (if any)
are used instead.
