Add endpoint for dashboard to collect logs (pprof) as zip file

We could also read the journal and display the logs in the dashboard.
example: https://github.com/coreos/go-systemd/blob/b14d3eb023cc860c82b1bb143bb98122d3c40224/sdjournal/journal_test.go

@muXxer Does this still make sense to do for v2.0.0-rc.1 ?

This needs support from hornet side, to make the zipped logs available through some endpoint.
No priority at the moment for this.
