The MX4J introspector does not support *MXBean interfaces name, This
causes a problem with the garbage collector and java related MBeans.
To bypass that limitation the APIMBeanIntrospector inherit from
MBeanIntrospector and override the relevant functionality so MXBean
will be treated like MBean.

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:

This patch changed how broadcast address is deduct. It Adds a reverse

find the ip address in use.
This implementation would probably be replaced by a single API call in
the future.

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.

Restart=always leads to the following loop:
1. scylla terminates abnormally
2. scylla-jmx sees that, and terminates
3. systemd sees that scylla-jmx terminated, and restarts it.
4. scylla-jmx requires scylla, so systemd starts it.
5. goto 1.
To prevent the loop, set Restart=on-abnormal; systemd will restart scylla-jmx
if some JVM bug got it killed, but not otherwise.
The downside to this patch is that if scylla-server goes down, so does
scylla-jmx, but if scylla-server is then restarted, scylla-jmx stays down.
To get scylla and scylla-jmx to start together, we need to create
scylla.service that requires both of them.
