Add os release collector

Currently Node Exporter has a metric called `node_uname_info` which of
course exposes uname info. While this is nice, it does not help if you
are running different OSes which could have similar uname info.

Therefore parse `/etc/os-release` or `/usr/lib/os-release` and expose a
`node_os_info` metric which provide information regarding the OS
release/version of the node. Also expose the major.minor part of the OS
release version as `node_os_version`.

Since the os-release files will not change often, cache the parsed
content and only refresh the cache if the modification time changes.

This `os` collector will read files outside of `/proc` and `/sys`, but
the os-release file is widely used and the format is standardized:
https://www.freedesktop.org/software/systemd/man/os-release.html
