Note: c3 adds configurable size threshold counting of messages sent,
dividing info "large"/"small" partitions (+gossiper). Message bulk
queries in v3 mbean reflects this.
Scylla does not (yet?) have such a threshold divider, so this is
highly incomplete and just delegates to old apis that "sort-of" fit.

The problem is rather innocent: the API call fails and we leak
javax.ws.rs.ProcessingException, which is not available in nodetool's
classpath. In fact, we already fixed the problem for GETs in commit
02e0598 ("APIClient: Fix error handling if connection to API server
fails") so do the same thing for POSTs.

Ran into this while trying to use ccm with not up-to-date scylla-jmx.
Symptoms:
$ ccm start
Error starting node node1
and empty ~/.ccm/scylla-3/node1/logs/system.log.jmx
Message-Id: <1468399926-3565-1-git-send-email-tgrabiec@scylladb.com>
The correct dependency between the jmx and the scylla-server is:
The scylla-jmx should not run if the scylla-server is not running, it
should shutdown when the scylla-server shuts down.
Starting the scylla-jmx should not start the scylla-server, instead, if
the scylla-server is not running it should fail to start.
This patch changes the setup to do so.

Commit 12daaf5 ("dist/redhat: fix rpm build error") did not fix the
error, at least not on our Jenkins build machines.
Looking at the RPM build logs, we create the build directory:
+ cd /builddir/build/BUILD
+ mkdir build
but then change directory to "scylla-jmx-1.2.rc1":
+ cd /builddir/build/BUILD
+ cd scylla-jmx-1.2.rc1
+ mvn install
and therefore fail the copy:
+ cp dist/common/systemd/scylla-jmx.service.in build/scylla-jmx.service
cp: cannot create regular file 'build/scylla-jmx.service': No such
file or directory
I don't know why Takuya put the "mkdir" in the "prep" section but
something like this should unblock the build.
When removing the pull based timers in the API the sum method in the
APITimer was left stubed by mistake.
This patch take the sum from the histogram as it should be.
Another missed changes are the units, in the yammer library the Timer
does unit conversion before returning the values.
This patch takes the unit conversion from the yammer library to be
compatible.

"This series uses the API that was added to scylla to remove the counter
pulling and rely on the statistics collected by the API.
The series extends the APIMeter, APIHistogram and APITimer to remove
their pulling part and to fetch the information when needed from the
API.
For performence reason those objects will be cached, so that in the
typical case of of multiple requests of different fields will cause a
single API call."

With the change in the meter implementation, retrieving a non existing
metrics would take time.
For this, the CacheService would mark caches that are not supported with
null url, so the metrics will be register but will return 0 for all
request (instead of going to the API that will return 0).

CacheMetrics is a general counter that is used for all possible caches.
For caches that we do not support, there is no need to go and fetch
their values.
When moving to the APITimer each such request will take longer (the
value will not be available as it use it) now it will be possible to
supply a null as a url which would cause to the metrics to return 0 for
all counters.

The yammer Timer object calculate rate based on a timer, which causes

With the move to APITimer, in many occasion a histogram will not update

This breaks the update values functionality so that a histogram that is
