Anton Tolchanov	5336362e64	prober: export probe class and metrics from bandwidth prober ... - Wrap each prober function into a probe class that allows associating metric labels and custom metrics with a given probe; - Make sure all existing probe classes set a `class` metric label; - Move bandwidth probe size from being a metric label to a separate gauge metric; this will make it possible to use it to calculate average used bandwidth using a PromQL query; - Also export transfer time for the bandwidth prober (more accurate than the total probe time, since it excludes connection establishment time).

Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	3 years ago
Anton Tolchanov	69f61dcad8	prober: add a DERP probe manager based on derpprobe ... This ensures that each DERP server is probed individually (TLS and STUN) and also manages per-region mesh probing. Actual probing code has been copied from cmd/derpprobe. Signed-off-by: Anton Tolchanov <anton@tailscale.com>	4 years ago
