v.6.19.7

Improvements:

1. [LUNA-6529] Field callbacks was added to notification policies. Each callback allows to send generated events to the third party system by specified url. Events sent using callback have corresponding format with ones from generate event resource. See generate events, create handler, validate handler policies.

2. [LUNA-6532] The generate stream events (beta) was updated without maintaining backward compatibility.
