CLOUDSTACK-9348: Reduce Nio selector wait time
This reduced the Nio loop selector wait time, this way the selector will
check frequently (as much as 100ms per iteration) and handle any pending
connection/tasks. This would make reconnections very quick at the expense of
some CPU usage.
/cc @swill @kiwiflyer guys can you please apply this fix in your env and
test if you're still able to produce any Nio related error b/w mgmt server(s)
and kvm agent(s) not being able to connect quickly. Please also watch out for
any increased CPU usage (there should not be any significant change), in which
case we may increase the timeout from 100ms to 200-400ms.
