With the change to APITimer there is no longer a need to periodically
pull the API.
The verb will be register on the object initialization and will be
updated whenever they are been used.

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).
Signed-off-by: Amnon Heiman <amnon@scylladb.com>
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
periodic calls to the API.
This replaces the implementation so that a timer would get all its

With the move to APITimer, in many occasion a histogram will not update
itself, instead it will be updated by the APITimer.
This breaks the update values functionality so that a histogram that is
included in an APITimer will not try to update it self.

This patch adds the functionality of takeMultipleColumnFamilySnapshot to
StorageService.
It follow origin logic of first check that all keyspaces and column
families exists and has no snapshot with that name and then run snapshot
on each of the combinations.
Two methods where added to simplify the implementation, but that can be
reused. One to get a map from keyspace to column family and one with the
current snapshots.

The version number ordering rules are different for rpm and deb. Use
tilde ('~') for the latter to ensure a release candidate is ordered
_before_ a final version.
When getting the tokens of the current node, we use the get_token api
call with the local broadcast address.
The current implementation that tries to figure it out from the
configuration is prone to error.
Currently in a configuration where the broadcast address is set to the
local API and the listening API is set to 127.0.0.1 we get a call to
nodetool info will return an exception:

Becasue getTokens will return an empty list.
This patch changed how broadcast address is deduct. It Adds a reverse
mapping from hostid to ip address and use it with the get local id to
find the ip address in use.
This implementation would probably be replaced by a single API call in
the future.
After the change a call to nodetool info works.
