Send OSGi event with execution details

[krystian-panek-vmltech]

it is rather not planned to share / expose contentor API.
to avoid versioning issues / compile-time dependencies etc

but still to be able to send notifications etc on script execution time OOTB OSGi eventing API could be used.
that hook may be useful in some integrations

probably not needed ; just leverage extension scripts
