While we keep ordinary hints in a directory parallel to the data directory,
we decided to keep the materialized view hints in a subdirectory of the data
directory, named "view_pending_updates". But during boot, we expect all
subdirectories of data/ to be keyspace names, and when we notice this one,
we print a warning:
WARN: database - Skipping undefined keyspace: view_pending_updates
This spurious warning annoyed users. But moreover, we could have bigger
problems if the user actually tries to create a keyspace with that name.
So in this patch, we move the view hints to a separate top-level directory,
which defaults to /var/lib/scylla/view_hints, but as usual can be configured.

"
Use perftune.py for tuning disks:
- Distribute/pin disks' IRQs:
- For NVMe drives: evenly among all present CPUs.
- For non-NVMe drives: according to chosen tuning mode.
- For all disks used by scylla:
- Tune nomerges
- Tune I/O scheduler.
It's important to tune NIC and disks together in order to keep IRQ
pinning in the same mode.
Disk are detected and tuned based on the current content of
/etc/scylla/scylla.yaml configuration file.
"
Fixes#3831.
* 'use_perftune_for_disks-v3' of https://github.com/vladzcloudius/scylla:
dist: change the sysconfig parameter name to reflect the new semantics
scylla_util.py::sysconfig_parser: introduce has_option()
dist: scylla_setup and scylla_sysconfig_setup: change paremeters names to reflect new semantics
dist: don't distribute posix_net_conf.sh any more
dist: use perftune.py to tune disks and NIC

Currently, build_deb.sh looks very complicated because each of distribution
requires different parameter, and we are applying them by sed command one-by-one.
This patch will replace them by Mustache, it's simple and easy syntax
template language.
Both .rpm distributions and .deb distributions have pystache (a Python
implimentation of Mustache), we will use it.

install(1) creates missing directories on recent Fedora, but not
on CentOS 7. This causes the RPM build (which installs to a pristine
tree, without an existing /etc) to fail.
Fix by setting up /etc.
Tests: rpm (Fedora, CentOS)

Move code to a traditional install.sh script (more traditional would be
a "make install", but this is close enough).
This allows testing installation independently of packaging. In addition,
non-Red Hat-packaging can share much of the code in install.sh.
Ref #3243.
Tests: build+install rpm
