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.

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.

"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
needs to be fixed to understand the "parallelism" and "incremental" options
passed to it.

Scylla's repair REST API (see scylla/api/storage_service.cc) takes all
repair options as one "options" string. The options are separated by ",",
and for each option, the name and value are separated by ":". The existing
code wrongly used "=" instead of ":", so this patch fixes it.
