Release 0.3.12 version

in order to easier the plot of that metric on Graphite.

Changelog:

Release 0.3.12 version

This release fixes 2 regression introduced in 0.3.11.

Changelog:
* Fix yet another regression introduced by 9e78b69

Release 0.3.11 version

With this release we provide TotalServers metric for backends which stores
the total number of servers configured in a backend. This closes unixsurfer#4.

We also compute standard deviation and percentiles for Idle_pct, which are
quite convenient for monitoring purposes.

Last but not least, we simplified the filtering for frontends/backends and
cleaned up some duplicate code.

Changelog:
* Compute standard deviation and percentiles for Idle_pct
* Sanitize values in pxname and svname columns
* Simplify the way we exclude frontends/backends
* Add TotalServer metrics for backend, close unixsurfer#4
* Update URI references for HAProxy documentation

Release 0.3.10 version

It fixes an issue with get coroutine which isn't cancelled when
it times out.

Changelog:
* Make sure we cancel get

Release 0.3.9 version

This release fixes a bug where we accidentally mess up the graphite top
namespace when 'namespace' setting is set a value which contains '.'
character(s).

We also fix a crash when daemon statistics are inconsistent, which can
only happen we pull statistics while HAProxy is being upgraded to
newer major release(1.5 -> 1.6) which exposes more metrics.

Changelog:
* Avoid replacing '.' with '_' in namespace setting
* Avoid crashing when daemon statistics are inconsistent
* Do a comparison to None singleton with is not
* Rename variable epoch to timestamp
* Place keywords in the same line
