2ff16fa2a5 scylla-jmx: set the APIBuilder in the command line
When setting the jmx through the command line, the jmx server creates
even before the main is called.
For the APIServer to take effect the builder should be set via system
properties.

This patch also add an option to run the java process with debug ports
open so an extern debug will be able to connect to the app.

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.

Fixes #28

c63ec3e96b StorageService: Add takeMultipleColumnFamilySnapshot support
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
When getting the tokens of the current node, we use the get_token api
call with the local broadcast address.

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.

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.

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.

So we're potentially losing a lot of information on our jmx service logs.
Let's update the log4j dependencies, and add the other ones that are
necessary for the logging to work.

3e1a8961a2 StorageService: setLoggingLevel
This patch uses the system api to set log level.
After this patch the nodetool setloglevel would support modifying a log
level of a log object.

24cebcc9a1 dist: do not always restart jmx on shutdown
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.
