When appying rate() to seconds we have 'seconds per second' or fractions of the second, so actually it actually can be from 0 to 1.
Also update intervalFactor to 1 for better rates.

rate() calculates per-second average rate, therefore Bps units should be used for disks.
In networking bandwidth throughput is usually measured in bits/s so units are changed accordingly.

These two memory classes have been here for a while now in FreeBSD,
adding them allows having information for all memory classes.

Log a single error message when the udev data directory (`/run/udev/data` by
default) is unreadable, and then don't try to get device properties out of it.
Also lower the log level from error to debug when we can't parse the udev files
properly, since these messages would be sent every time the node exporter gets
scraped.

When parsing udev data, skip lines that don't start with `E:`.
Lines prefixed with `E:` represent device properties, as documented in
udevadm(8).

Set the `--path.udev.data` flag to point to the udev fixture, and update the
output fixture with
```console
$ ./end-to-end-test.sh -u
```

Now that we read some data from `/run/udev/data`, add the corresponding
fixtures and update the expected test results accordingly.

Instead of hard-coding the path to `/run/udev/data`, intoduce a
`--path.udev.data` flag that defaults to that value.

Add labels to the `node_disk_info` metric extracted from udev, such as `model`,
`path`, `revision`, `serial` and `wwn`.
Also add a few metrics related to filesystem and device mapper, which are also
extracted from udev information.
