Extended show pools (#135) 
* Extended show pools

* Output time quantiles in SHOW POOLS EXTENDED

One important caveat is that quantiles itself will be taken from console database.
But if route does not have quantiles defined all stats will be zero.

* Change quantile refresh period

Dmitry Simonenko 2e03af9c88 odyssey: major router and shared logic rework 
Goal is to improve overall performance during massive peaks
of connecting clients.

This patch makes router a shared structure, instead of
being run in separate system worker thread/coroutine.

Now router and each route object is protected by
separate mutex. Worker threads directly access router object
without calls to separate thread.

Dmitry Simonenko da7e6ea7a5 odyssey: major io rework and refactoring 
This patch moves Odyssey from stream based write caching
to message driven. All write operations are delayed
and happen on a group of messages.

This removes necessity to do IO and wait for write completion during calls
from SSL_write() context. Write timings should behave more predictable now and
number of used syscalls should be also decreased.

This patch also simplifies caching management. All clients are simply
reusing cached messages without prolonged contention.

Several configuration options are no longer used:
pipeline, cache, cache_chunk
