Today, Multus will always log via STDERR, and these logs will then
logged by the Kubelet. If we also choose to have Multus log to a file by
setting the LogFile option in the CNI configuration, the same logs will
be logged twice.
This commit provide the option to disable logging to STDERR.

When we call mergeRuntimeConfig, the global RuntimeConfig gets
overwritten with the result of the merging, thus affecting the
subsequent delegates.
Do not modify the global RuntimeConfig and instead make a copy
when merging it.
Also, if a value has been provided for CNIDeviceInfoFile in the
delegate's runtimeconfig, overwrite it to avoid possible name
colissions.
