So that do_before_change_notifications and do_on_change_notifications
are under seastar::async.

825f6d141d gossip: Run code inside seastar::async context for apply_state_locally 
It is easier to futurize apply_new_states and handle_major_state_change.

Now, on_change, on_join and on_restart callbacks are inside
seastar::async context.

Otherwise, when a node tries to send to a just killed node, it will
block for a long time, thus gossip round will be blocked.

baec9e3449 gossip: Fix is_enabled 
It is not correct to use _scheduled_gossip_task.armed() to tell if
gossip is enabled or not , since timer set _armed = false before calling
the timer callback.

It was working correctly because we did not actually check is_enabled()
flag inside the timer callback but inside the send_gossip_digest_syn()'s
continuation and at that time the timer is armed again.

Use a standalone flag to do so.

1da37796bc gossip: Fix do_shadow_round 
We sleep storage_service_ring_delay until we abort due to failing to
talk to a seed node. We should retry sending GossipDigestSyn message,
instead of sending it once.

With this, we can start the seed node and normal node in a script like
below, without any sleep between.

./scylla --listen-address 127.0.0.1
./scylla --listen-address 127.0.0.2

This is useful for testing.

0ce3d89a85 gossip: Switch to use chrono for time operation 
This is a long-awaited cleanup. Gossiper code runs every second, it is
not performance sensitive, so it does not make much sense to stick to
lowres db_clock, use high_resolution_clock instead.

74b281b92a gossip: Fix QUARANTINE_DELAY initialization 
Dependencies between static variables don't work if they're in different
translation units.

I see in gossiper's constructor, QUARANTINE_DELAY is still 0.

Make it a function. It is nicer to make it inline, but I don't want to
pull storage_service.hh into gossiper.hh.
