public default GraphComputer configure(final String key, final Object value) {
        return this;
    }
Set an arbitrary configuration key/value for the underlying {@code Configuration} in the {@link GraphComputer}.
Typically, the other fluent methods in {@link GraphComputer} should be used to configure the computation.
However, for some custom configuration in the underlying engine, this method should be used.
Different GraphComputer implementations will have different key/values and thus, parameters placed here are
generally not universal to all GraphComputer implementations. The default implementation simply does nothing
and returns the {@link GraphComputer} unchanged.

@param key   the key of the configuration
@param value the value of the configuration
@return the updated GraphComputer with newly set key/value configuration
