This closes #1612
> Session should not copy FlowFile Attribute Map when creating new FlowFile

> Fix For: 1.2.0
>
>
> Currently, each time we create a new FlowFile object, we do so using
> StandardFlowFileRecord.Builder and then call fromFlowFile(FlowFile). This
> copies the attributes map of the given FlowFile. We should instead just set
> the member variable of the builder to point at the same Map object as the
> given FlowFile and keep a flag indicating whether or not this was done. If
> this is done, we must lazily copy the hash map before modifying it.
> Otherwise, we can point to the same Map object.
