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.

The ntp collector has always been a source of confusion and problems.
The data it produces is more of a blackbox probe against an NTP server.
The time sync / offset data produced is not what users expect.
Mark this collector as deprecated to be removed in v2.0.0

Some systems have broken netlink messages due to patched kernels. Since
these messages can not be parsed, add a flag to fall back to parsing
from `/proc/net/dev`.

Note however that the InetDiagMsg struct contains a InetDiagSockID
member, which itself contains some members which are explicitly
specified as big-endian in Linux kernel source:
struct inet_diag_sockid {
__be16 idiag_sport;
__be16 idiag_dport;
__be32 idiag_src[4];
__be32 idiag_dst[4];
__u32 idiag_if;
__u32 idiag_cookie[2];
};
node_exporter currently does not use these members for anything, so this
is acceptable (for now).
