rtmp2src: add 'no-eof-is-error' property

Browse source 
There is currently no way for applications to know if the stream has
been properly terminated by the server or if the network connection
was disconnected as EOS is sent in both cases.

Adding a property so connection errors can be reported as errors
allowing applications to distinguish between both scenarios.

Fix #2828
