We were ignored --smp option taken from io.conf since iotune didn't supported
it, but now it supported we can pass it.
(We need to pass it because we need to measure io performance on same condition
with scylla)

EC2 paravirtual instances uses pv-grub, which refers /boot/grub/menu.lst (grub0.9x config file) instead of grub2 config file.
So add boot parameters on /boot/grub/menu.lst when the file exists, and the instance is on EC2.

On Debian, lsb_release -r returns the version number something like '8.6'.
However, on this script we want to check major version only.
Therefore we can use VERSION_ID from /etc/os-release which only contains

The expected behaviour in the scylla_setup script is that a question
will be followed by the answer.
For example, after asking if the scylla should be run as a service the
relevant actions will be taken before the following question.
This patch address two such mis-orders:
1. the scylla-housekeeping depends on the scylla-server, but the
setup should first setup the scylla-server service and only then ask
(and install if needed) the scylla-housekeeping.
2. The node_exporter should be placed after the io_setup is done.

In order to allow Scylla’s docker container to handle multiple network
interfaces, the start-scylla script was refactored:
- `$IP` is now called `$SCYLLA_LISTEN_ADDRESS`, so it is less likely to
be confused or interfere with other environment variables.
- `$SCYLLA_LISTEN_ADDRESS` now checks its value and also tries to
resolve a hostname, if no IP was set to it.
- `$SCYLLA_LISTEN_DEVICE` can now be set as environment variable and
contain any available NIC device name (e.g. `eth0`). The script
automatically retrieves the IP address from the device.
Usage:
1. With `$SCYLLA_LISTEN_ADDRESS` as IP:
`docker run -t -i --rm --name scylla -e SCYLLA_LISTEN_ADDRESS=192.168.1.100 scylladb/scylla`
2. With `$SCYLLA_LISTEN_ADDRESS` as hostname:
`docker run -t -i --rm --name scylla -e SCYLLA_LISTEN_ADDRESS=containername.network.lan scylladb/scylla`
3. With `$SCYLLA_LISTEN_DEVICE`:
`docker run -t -i --rm --name scylla -e SCYLLA_LISTEN_DEVICE=eth0 scylladb/scylla`

node_exporter is a utility that export node information via prometheus
API. It takes care of host related metrics such as CPU and memory.
The install script, download the node_exporter binaries, create a link
in /usr/bin.
On OS with systemd supported it would enable and start the installed
service file to start as a service. On others (ubuntu) it would create a conf file and start it.
The installation should be done using sudo.
After a successful installation, the node_exporter would run as a
service.

On posix_net_conf.sh's single queue NIC mode (which means RPS enabled mode), we are excluded cpu0 and it's sibling from network stack processing cpus, and assigned NIC IRQ to cpu0.
So always network stack is not working on cpu0 and it's sibling, to get better performance we need to exclude these cpus from scylla too.
To do this, we need to get RPS cpu mask from posix_net_conf.sh, pass it to scylla_cpuset_setup to construct /etc/scylla.d/cpuset.conf when scylla_setup executed.

Right now scylla_prepare specifies -mq option to posix_net_conf.sh when number of RX queues > 1, but on posix_net_conf.sh it sets NIC mode to sq when queues < ncpus / 2.
So the logic is different, and actually posix_net_conf.sh does not need to specify -sq/-mq now, it autodetects queue mode.
So we need to drop detection logic from scylla_prepare, let posix_net_conf.sh to detect it.

Aug 25 19:44:51 scylla1 scylla[637]: Exiting on unhandled exception of type 'std::system_error': Error system:99 (Cannot assign requested address)
The problem is that because there's no dependency to network service,
Scylla simply attempts to start up too soon in the boot sequence and
fails.
