Set forward context for events having a different instanceId

The high-availability plugin has a concept of forwarded event.
This is modelled as a Context property and it is checked on
the receiving side of the plugin, so that received events are
flagged as forwarded and not re-forwarded.

Set the forward context at the _producing_ side as well, so that events
that were received through different channels (i.e. multi-site) are not
re-forwarded.

The event source check is done by checking whether the event payload
carries the instanceId of a gerrit instance different from the current
one.
