Refactor os-release and platform information
Move the /etc/os-release parser and platform detection code out of the
private _importhook module. The ipaplatform module now contains an
osinfo module that provides distribution, os, and vendor information.

See: https://www.freedesktop.org/software/systemd/man/os-release.html
