Debian package builds provide a root environment for the installation
scripts, since that's what typical installation scripts expect. To
avoid providing actual root, a "fakeroot" system is used where syscalls
are intercepted and any effect that requires root (like chown) is emulated.
However, fakeroot sporadically fails for us, aborting the package build.
Since our install scripts don't really require root (when operating in
the --packaging mode), we can just tell dpkg-buildpackage that we don't
need fakeroot. This ought to fix the sporadic failures.
As a side effect, package builds are faster.

(cherry picked from commit 626fd75173)
On the commit 4c8660d, we dropped /usr/lib/scylla/jmx since it likely no user
script invoke scripts under the directory.
However, we found there are possibility scylla-jmx.service tries to load .jar
file from /usr/lib/scylla/jmx, when user upgraded from older version of scylla.
Because /etc/sysconfig/scylla-jmx is marked as 'noreplace' on our rpm,
yum upgrade may keep old sysconfig file when it modified by user, that may
causes to load .jar from /usr/lib/scylla/jmx since we specify the path in the
sysconfig file.
To avoid the issue it's better to have symlinks on /usr/lib/scylla/jmx for
safety.
See #90
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.

Same as 301c835cbf,
Fedora 31 switched the default compression to zstd, which isn't readable
by some older rpm distributions (CentOS 7 in particular). Tell it to use
the older xz compression instead, so packages produced on Fedora 31 can
be installed on older distributions.

Add myself as a "code owner" so that I am assigned a review
automatically:
https://help.github.com/en/github/creating-cloning-and-archiving-repositories/about-code-owners
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.

Since the incoming json uses swagger "key", "value" syntax
we need to do explicit deserialization of this property
as well (not just extended props).

"This is nonroot installer patchset v4, for scylla-jmx."
* '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.

There's an effort to implement a version of "nodetool" that uses
Scylla's REST API directly, Let's make the API client a separate module,
so nodetool can use it.

Since we cannot use dh --with=systemd because we don't want to
automatically enabling systemd units, manage them by our setup scripts,
we have to do 'systemctl daemon-reload' manually.
(On dh --with=systemd, systemd helper automatically provides such
