Fix include_clients in PostfixCollector
Use str_to_bool instead
add connected clients metric
Add multiple instance support to mongodb collector

Users can now define a list of hosts and collector will be fetching
metrics from all of them. This is useful when you run several mongo
instances on the same host (shard server and configuration server, for
example).

The change is backwards-compatible.

fix metric_types for beanstalkd

When setting up beanstalkd with a Librato handler, I noticed that it
wasn't reporting the metric types correctly. This patch will whitelist
stats that are known to be counters (tested with beanstalkd 1.4.6) and
default to GAUGE for everything else.

fix metric_types for beanstalkd
default metric_type to GAUGE

While setting up Librato, I noticed that multiple collectors are not
setting the metric_type parameter (important ones, such as cpu and
network), and thus getting the default of COUNTER. They then getting
recorded wrong and show up as a flat graph. I think COUNTER is the
wrong default, as most metrics collected by Diamond are actually of
GAUGE type. It is also much easier to tell when a counter is accidently
being reported as a guage than when a gauge is being reported as a
counter.
