This patch fixes the regression introduced by 3a51e78 which broke
a very important contract: perftune.yaml should not be "touched"
by Scylla scriptology unless explicitly requested.
And a call for scylla_cpuset_setup is such an explicit request.
The issue that the offending patch was intending to fix was that
cpuset.conf was always generated anew for every call of
scylla_cpuset_setup - even if a resulting cpuset.conf would come
out exactly the same as the one present on the disk before tha call.
And since the original code was following the contract mentioned above
it was also deleting perftune.yaml every time too.
However, this was just an unavoidable side-effect of that cpuset.conf
re-generation.
The above also means that if scylla_cpuset_setup doesn't write to cpuset.conf
we should not "touch" perftune.yaml and vise versa.
This patch implements exactly that together with reverting the dangerous
logic introduced by 3a51e78.

To make scylla setup scripts easier to handle in Ansible, stop deleting
perftune.yaml and detect cpuset.conf changes by mtime of the file.
Also, skip update cpuset.conf when same parameter specified.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
scylla_setup resets our configuration and perftune.yaml is a part of it.
perftune.yaml is generated based on the contents of cpuset.conf therefore we should reset
these together.

The scylla_cpuset_setup uses a verify_args() function that is defined in the scylla_lib.sh.

When user mistakenly forgot to pass parameter for a flag, our scripts misparses
next flag as the parameter.
ex) Correct usage is '--ntp-domain <domain> --setup-nic', but passed
'--ntp-domain --setup-nic'.
Result of that, next flag will ignore by scripts.
To prevent such behavior, reject any parameter that start with '--'.

These parameters are only required for AMI, not for non-AMI environment which want to enable SET_NIC, so split them to indivisual script / conf file, call it from AMI install script.
