The textfile collector will now provide a unified metric description
(that will look like "Metric read from file/a.prom, file/b.prom")
for metrics collected accross several text-files that don't already
have a description.
Also change the error handling in the textfile collector tests to
ContinueOnError to better mirror the real-life use-case.

* Allow user to select port on NTP server to query
Some people (me!) run NTP servers on non-privileged ports. The `github.com/beevik/ntp` package allows overriding the port, so this change just adds a flag `collector.ntp.server-port` (defaults to 123) and then passes that value through to the query via the `QueryOptions`.

On Linux, we get more detailed interface statistics from netlink than we did
from `/proc/net/dev`.
This commit adds a new flag (`--collector.netdev.enable-detailed-metrics`) to
expose those statistics under new (incompatible) metric names. When enabled,
the metric names are also changed on Darwin and BSD platforms to keep
everything consistent, but it doesn't provide more detailed statistics on those
platforms.
The old metrics can be derived from the new ones using the following rules
([dev_seq_printf_stats]):
- `receive_errs` = `receive_errors`
- `receive_drop` = `receive_dropped` + `receive_missed_errors`
- `receive_fifo` = `receive_fifo_errors`
- `receive_frame` = `receive_length_errors` + `receive_over_errors` + `receive_crc_errors` + `receive_frame_errors`
- `receive_multicast` = `multicast`
- `transmit_errs` = `transmit_errors`
- `transmit_drop` = `transmit_dropped`
- `transmit_fifo` = `transmit_fifo_errors`
- `transmit_colls` = `collisions`
- `transmit_carrier` = `transmit_aborted_errors` + `transmit_carrier_errors` + `transmit_heartbeat_errors` + `transmit_window_errors`

To prepare for the introduction of new metric names, add tests for the legacy
metric names and values. This will make it easier to ensure that the code that
converts the new metrics to the old ones (for compatibility) behaves correctly.

Since netdev metrics are now read from netlink instead of `/proc/net/dev`, we
can't easily spoof them for the end-to-end tests by reading a fixture file in
place of `/proc/net/dev`.
Therefore, we only get metrics for `lo` and ignore those that would return
unpredictable values (i.e. the byte and packet counters).

Instead of parsing `/proc/net/dev` to get network interface statistics, get
them from a netlink call.
Internally, both come from the [rtnl_link_stats64] struct, but with
`/proc/net/dev`, some of the values are aggregated together in
[dev_seq_printf_stats], so we get less information out of them.
This commit maintains compatibility by aggregating those stats back into the
same metrics.

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).
