Fix compatibility issues with Java 1.8 Map
Java 1.8 Map implements default methods - remove(K, V), which conflicts
with the remove(String, V) in gov.nist.core.MultiMapImp. This changes
deletes the method from the interface - gov.nist.core.MultiMap
as well as from the implementation in gov.nist.core.MultiMapImp as no
caller were found for the same.
Bug: 27426743

- * This is simply a Map with slightly different semantics.

- * So for example, you can put( key, new Integer(1) );

- * instead of an Integer.
