Utility method which copies all entries from source into target. Entries with the same keys from target will be
overridden with entries from source. This operation is similar to {@link Map#putAll(Map)}, but it doesn't require
changing generics to construction like

<pre>
<? extends String, ? extends S>
</pre>

@param source
the map from where the entries will be copied into target.
@param target
the map where to put entries from source.
