This change adds the ability to process multiple stat calls in parallel.
Processing is rate-limited based on the new flag
`collector.filesystem.stat-workers` (default 4).
Caveat: filesystem stats information is no longer in the same order as
returned by `/proc/1/mounts`. This should not be an issue.
Caveat: This change currently uses unbuffered channels to prove
correctness without reliance on buffers. Buffered channels will yield
superior performance.

Read missing dev_id, name_assign_type, and addr_assign_type
from sysfs, since they only take a device-specific lock and
not the whole RTNL lock. This means reading them is much less
impactful on other system processes than many of the other
attributes in sysfs that do take the RTNL lock.

On most hard drives, `ID_SERIAL_SHORT` and `SCSI_IDENT_SERIAL` are identical,
but on some SAS drives they do differ. In that case, `SCSI_IDENT_SERIAL`
corresponds to the serial number printed on the drive label, and to the value
returned by `smartctl -i`.
So use that value by default for the `serial` label on the `node_disk_info`
metric, and fallback to `ID_SERIAL_SHORT` only if it's undefined.

Use the filesystem collector for all OpenBSD archs, there is no reason to
only use it on amd64 systems.

This updates the annotation for the NodeClockSkewDetected mixin alert to
match the new threshold set.
Original discussion was in this PR: https://github.com/prometheus/node_exporter/pull/1480
I spent an embarrassingly large amount of time trying to figure out how
the heck that alert would mean 300s of clock skew. Turns out the
annotation was just left the same after the threshold change.
