adf466519f APIClient: Support for non pull APIMeter
APIMeter will be modified not to use pulling and to retrieve the derived
information from the API.

To support that the APIClient was changed so it would be able to cache
json objects and histogram.

853963f833 APIMBeanServer: overload the queryName implementation
The mx4j implementation of queryName does not handle correctly pattern
matching.

This patch identify that a name contains a patern and do the patern
matching as it should have been done by the mx4j MBeanServer.

4e02c52aee Adding the APIMBeanServer
The APIMBeanServer is serve as a proxy for the MBeanServer.
It intercept calls to the MBeanServer and check for the column family
and stream registeration before they are perform.

Current implementation override queryNames as it's the one that is being
used by nodetool.

Additional methods can be override in the future if needed.

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.

94f144e9b3 StorageService: Get the broadcast address from the API

nodetool info will return an exception:

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.

02e0598506 APIClient: Fix error handling if connection to API server fails
Running 'nodetool status' now reports the following if the JMX proxy is
not able to connect to an API server:

  nodetool: Unable to connect to Scylla API server: java.net.ConnectException: Connection refused
  See 'nodetool help' or 'nodetool help <command>'.

instead of the scary-looking:

  error: javax.ws.rs.ProcessingException (no security manager: RMI class loader disabled)
  -- StackTrace --

          at sun.rmi.server.MarshalInputStream.resolveClass(MarshalInputStream.java:214)

That happens because the MBean propagates a
'javax.ws.rs.ProcessingException' to nodetool which does not have it in
it's classpath and loading via RMI fails.

15ad444c40 scylla-jmx: implement forceRepairRangeAsync
Fix the stubbed implementation of forceRepairRangeAsync() which is
used, for example, when the "--start-token"/"--end-token" options are
passed to "nodetool repair".

forceRepairRangeAsync() works similarly to the existing forceRepairAsync()
just sending the additional start/end tokens as two new options to the
REST API. Unlike the parallel Cassandra code, we don't do any fancy
processing on these tokens to intersect them with the node's token ranges -
we'll do this intersection in the C++ code, where the repair is actually
done.

"nodetool repair" ends up calling one of the dozen forceAsyncRepair()
functions. This function ignored its option rather than passing it on,
so this patch fixes that.

Note that there are still many more forceAsyncRepair() overloads which
similarly ignore their options, and it is possible that certain invocation
of "nodetool repair" will need them, so we will need to fix all of them
in the future.

After this patch, "nodetool repair" no longer works because now Scylla

649922fed8 Updating the http client and support API exception
The API returns errors with an HTTP code 400, 404 or 500 depending on
the cause with a json object that contains the failure reason.  The
error message should be populate to the JMX calling client, translated
to the appropriate exception.

This patch adds the ability to detect API failure and throw a runtime
exception with the returned message.

It is up to the calling method what to do with the exception, if it
would do nothing, the calling client would get a RuntimeException,
depends on origin MBean definition, the caller can catch the exception
and throw a specific kind.

Note that any exception that is thrown must be known to the JMX client
or it will not be able to process it.

As a first step, this patch replaces the jersey client to the newer
version under glassfish, which has an easy way of getting a Reply
object, and check its status before returning the results.

The only difference in the method that uses the APIClient is the use of
MultivaluedHashMap.

ColumnFamily

3667682075 ColumnFamilyStore: add support for estimated latency
This patch uses the estimated latency that was added to the column
family metrics to get the recent and estimated latency.

It follows the same logic as origin does to call the logic in metrics.

The following method implementation will be added:

getMemtableColumnsCount
getRecentSSTablesPerReadHistogram
getSSTablesPerReadHistogram
getLifetimeReadLatencyHistogramMicros
getRecentReadLatencyHistogramMicros
getRecentReadLatencyMicros
getLifetimeWriteLatencyHistogramMicros
getRecentWriteLatencyHistogramMicros
getRecentWriteLatencyMicros
getRangeCount
getTotalRangeLatencyMicros
getLifetimeRangeLatencyHistogramMicros
getRecentRangeLatencyHistogramMicros
getRecentRangeLatencyMicros

960aa6f509 LatencyMetrics: Support totalLatencyHistogram and recentLatencyHistogram
This adds the depricated total and recent estimated histogram.
It uses the new RecentEstimatedHistogram for the recent value and the
API based estimated histogram for the total latency.

6df716e5f7 Add an EstimateHistogramWrapper
The EstimatedHistogramWrapper is a helper class that holds the API
related data, so that a class that uses an EstimatedHistogram can
replace it with the wrapper and keep most of its code as is.

a7c30493cd APIClient to support EstimatedHistogram
This patch modify the CacheEntry to support both String and
EstimatedHistogram.

It is possible to add more supported types in the future when needed.

In the APIClient, the cache will now support both String and
EstimatedHistogram in a similiar way.

a568e52cb5 Adding the RecentEstimatedHistogram
Some of the jmx methods uses the notion of recent estimated histogram.
In origin the implementation uses an estimated histogram and clean the
histogram values on each call.

The RecentEstimatedHistogram mimic this behaviour, it store the latest
values of the last call. In each call new values are stored in the
histogram and the results is the delta between the last two calls.
