What does this PR do?

Add os information to telemetry

Motivation

https://datadoghq.atlassian.net/browse/APMSP-2308

Additional Notes

What's the policy around unsafe ? Is there a better way to get uname information without using external crates that do just this but abstracted and increasing the package size ?

Kernel name

Python implem

platform.system():

Returns the system/OS name, such as 'Linux', 'Darwin', 'Java', 'Windows'. An empty string is returned if the value cannot be determined.

On iOS and Android, this returns the user-facing OS name (i.e, 'iOS, 'iPadOS' or 'Android'). To obtain the kernel name ('Darwin' or 'Linux'), use os.uname().

https://docs.python.org/3/library/platform.html#platform.system

This implem

sys_info::os_type():

Get operation system type.

Such as “Linux”, “Darwin”, “Windows”.

https://docs.rs/sys-info/latest/sys_info/fn.os_type.html

Kernel release

Python implem

platform.release():

Returns the system’s release, e.g. '2.2.0' or 'NT'. An empty string is returned if the value cannot be determined.

https://docs.python.org/3/library/platform.html#platform.release

This implem

sys_info::os_release():

Get operation system release version.

Such as “3.19.0-gentoo”

https://docs.rs/sys-info/latest/sys_info/fn.os_release.html

Kernel version

Python implem

platform.version():

Returns the system’s release version, e.g. '#3 on degas'. An empty string is returned if the value cannot be determined.

On iOS and Android, this is the user-facing OS version. To obtain the Darwin or Linux kernel version, use os.uname().

https://docs.python.org/3/library/platform.html#platform.version

This implem

Unix

I tested in on mac and linux docker, and both python and rust implem return a string equivalent to uname -v from man uname.1

libc::uname().version

char version[]; /* Operating system version */

man uname.2

Windows

"{major}.{minor}.{build}"

https://crates.io/crates/winver
