This is scylla-jmx part of https://github.com/scylladb/scylla/pull/5530
After we stopped replacing /usr/lib/scylla with symlink,
creating symlink on /opt/scylladb/scripts/jmx become meaningless,
so we can drop it now.
We able to introduce new symlink on /usr/lib/scylla, but it likely no user
directly invoke scripts under /usr/lib/scylla/jmx, so we don't have to
do that.

Since Debian 10 dropped OpenJDK 8, so we need to switch to other
JVM distribution which still maintain OpenJDK 8 for Debian.
We can use AdoptOpenJDK for such environment.

Since Debian variants can install multiple JRE, "Depends: openjdk-8-jre" may
not mean default JRE is openjdk-8.
We should block openjdk-11 for now, until we support it.

Add myself as a "code owner" so that I am assigned a review
automatically:

I also wanted to add Amnon and Calle, but apparently you need to have
write permissions in order to be a code owner.
The purpose of this automation is to ensure Scylla JMX pull requests
show up in my github.com/pulls page. Thanks Maciej Zimnoch for the tip!
Scylla now supports server-defined systemd slices that are used to provide
isolation between components.
This patch adds scylla-jmx to the helper slice. This will guarantee that
scylla-jmx does not use too much resources, influencing the server performance.

Takuya had untemplataize scylla-jmx.service in commit e8355087ea
But the build_deb.sh still tries to generate service file from a deleted
mustache template file -- scylla-jmx.spec.mustache. It wrongly redirects
a path to service file, then scylla-jmx would fail to start.

* 'nonroot_v4' of https://github.com/syuu1228/scylla-jmx:
install.sh: add --nonroot mode
dist/common/systemd: untemplataize *.service, use drop-in units instead
dist: move package build script to install.sh
Since systemd unit can override parameters using drop-in unit, we don't need
mustache template for them.
Also, drop --disttype option on install.sh since it does not required anymore,
introduce --sysconfdir instead for non-redhat distributions.
Move package build script from .rpm/.deb to single script, install.sh.
We need this to support nonroot mode, and also to keep package build script
consistent between .rpm/.deb.

Cassandra 3.0 version of the JMX added a parameter that allows accepting
the parameter as hex.
This breaks the current implementation with a NoSuchMethodException.
This patch adds the missing implementation.
For a full support, a follow up patch in Scylla is needed, but for the
current functionality it would work.

Scylla's REST API directly, Let's make the API client a separate module,

Since we cannot use dh --with=systemd because we don't want to

we have to do 'systemctl daemon-reload' manually.

When we add product name customization, we mistakenly defined the
parameter on each package build script.
Number of script is increasing since we recently added relocatable
python3 package, we should merge it in single place.
Also we should save the parameter on relocatable package, just like
version-release parameters.
So move the definition to SCYLLA-VERSION-GEN, save it to
build/SCYLLA-PRODUCT-FILE then archive it to relocatable package.

This patch adds the implementation for begin and finish local sampling
of a column family.
There is a difference in the implementation of Cassandra API and Scylla.
In Cassandra and the JMX an external source start and stop the sampling.
In Scylla, a single API call start the sampling and return with the
result. In Scylla the API call always return sampling of the read and of
the writes.
To bridge the difference, the begin sampling command will use a Future
when calling the API. The finish method will wait for the future to end.
Because of the different implementation, it is possible that two
consecutive calls will be made to start sampling one for the read and
one for the write, similarly, two calls will be made to finish for read
and write.
The implementation would ignore the second call to start and will
store the result, so the second call to finish will be served from the
stored result.
Note, that the use of future is only for safety, the way we expect it to
work, the caller to the begin sampling will sleep anyhow while waiting
for the result.
To avoid breaking the MBean compatibility we piggyback the duration on
top of the sampler string.
If no duration is given, a default duration will be taken, this is also
just as a precaution, we will modify the nodetool implementation to
pass that information.
There is a known issue with cardinality, that will need to be addressed.
Also we return a value in the raw column to match what Cassandra JMX
returns, but it's a duplication of the partition key.

But Fedora 28's python2-pystache has tag "Provides: pystache",
