Since we moved to Java 8, we need to provide additional repository for
distributions which doesn't have Java 8 on default repository.

"This series change getTokenToEndpointMap implementation, so that the result
will be sorted by the API.
The API returns the tokens sorted according to their type. The APIClient helper
method was change to keep the original order and getTokenToEndpointMap was
change so it will return the map as is, without re-sorting it."
It normally won't be problem because scylla-jmx usually build after scylla building.
However some tools we required for build_deb.sh doesn't installed on minimal installation, so we should check and install it.

build_deb.sh fails to run because git-archive-all doesn't have execution bit,
to prevent build error we need to add the bit.

This patch change the sorting of tokensEndpointMap so it will use the
order returned by the API.

The getMapStrValue return a map from the API. This change the
implementation to use linkedHashMap so the map will be sorted according
to the API order.

The nodetool looks for column family with by their name. When using
JConsole, it search for all MBeans.
This patch adds a check for column family and stream with null query
(wild card).
This way the column family will appear in the JConsole.

"This is a pretty hefty change set. Base goal is to update JMX impl to
Cassandra 3.x compatibility. While the base MBeans are easy enough, the
metrics parts of the stew are trickier, since Cassandra 3 changed a
number of things around. To that end, and to clean up this code
somewhat, this basically changes all about metrics management in
scylla-jmx. Some background:
Cassandra uses codehaul metrics for actual measurement. Now,
obviously, in this proxy project we need not measure anything, since
actual happenings are in the Scylla process. Previous version of the
code however still utilized a (not-so-pretty reflection-hacked-into)
version of codehaul metrics because they also provided the system for
exposing the data through JMX. I.e. we added a bunch of stuff we
really did not need, to avoid dealing with some of that we did.
In Cassandra 3, v3 of codehaul is used, which the Cassandra devs
apparently did not like the JMX integration of. Thus they decided to
deal with JMX exposure themselves. which makes sense, because they
want to control the syntax/structure. But given this, we no longer
have any reason to utilize codehaul, since it does nothing for us.
These change sets instead adapts the cassandra JMX bindings somewhat,
and adds a wholly own structure of metric point binding, using
java.util.function interfaces to provide flexible and late-ish binding
to actual data query objects. End result is a much slimmer set of
objects/functions to bind metrics (which of course are just queries to
Scylla API).
Also, MX4J has been dropped, since it is at best broken. Instead, we
use simple wrapping of the system management server object to deal with
dynamically populating transients objects like column families.
Removed most statefulness (beyond binding) in MBean impls, all
"bookeeping" of sub-objects and bind status now uses the actual mbean
server. I.e. remove race conditions + lighter bookkeep.
Since this is Java, and everything is tied together in a ball of yarn,
most of the changes here are not self-contained. I.e. some of these
will, applied individually, break the build. They are still kept as
individual patches though, mainly for readability."
This series fill some missing functionality by using already existing
API.
The idea is to use existing code in places that it was not used.
Also, in places were a stub value is in place, the methods returns a
stab value.

Implement some deprecated metrics in CommitLog and CompactionManager,
that can easily just be a wrapper to the non-deprecated metrics API.

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.
