Introducing extended app process management.
- Pre-fork 'processes.spare' application processes;
- fork more processes to keep 'processes.spare' idle processes;
- fork on-demand up to 'processes.max' count;
- scale down idle application processes above 'processes.spare' after
'processes.idle_timeout';
- number of concurrently started application processes also limited by
'processes.spare' (or 1, if spare is 0).
