cmd, metrics: add support for influxdb-v2 (cherry-picking from italoacasas' changes), leave existing support for v1 to maintain backwards-compatibility. (#23194)

This PR adds flag to enable InfluxDB v2 (--metrics.influxdbv2), flags for v2-specific features (--metrics.influxdb.token, --metrics.influxdb.bucket), also carries over addition of support for specifying organization (--metrics.influxdb.organization), but still retains backwards compatibility with InfluxDB v1.

Fixes #11113

fixes an regression which caused build failure on certain platforms

* remove uneeded convertion type

* remove redundant type in composite literal

* omit explicit type where implicit

* remove unused redundant parenthesis

* remove redundant import alias duktape

* cmd/geth: dump config

* cmd/geth: dump config

* cmd/geth: properly read config again

* cmd/geth: override metrics if flags are set

* cmd/geth: write metrics regardless if enabled

* cmd/geth: renamed to metricsfromcliargs

* metrics: add default configuration

* metrics: zero temp variable in  updateMeter

Previously the temp variable was not updated properly after summing it to count.
This meant we had astronomically high metrics, now we zero out the temp whenever we
sum it onto the snapshot count

* metrics: move temp variable to be aligned, unit tests

Moves the temp variable in MeterSnapshot to be 64-bit aligned because of the atomic bug.
Adds a unit test, that catches the previous bug.

Exposing /debug/metrics and /debug/metrics/prometheus was dependent
on --pprof, which also exposes other HTTP APIs. This change makes it possible
to run the metrics server on an independent endpoint without enabling pprof.

* replace gosigar with gopsutil

* removed check for whether GOOS is openbsd

* removed accidental import of runtime

* potential fix for difference in units between gosig and gopsutil

* fixed lint error

* remove multiplication factor

* uses cpu.ClocksPerSec as the multiplication factor

* changed dependency from shirou to renaynay (#20)

* updated dep

* switching back from using renaynay fork to using upstream as PRs were merged on upstream

* removed empty line

* optimized imports

* tidied go mod

* metrics/prometheus: define type once for histograms

* metrics/prometheus: test collector

The test failed due to what appears to be fluctuations in time.Sleep, which is
not the actual method under test. This change modifies it so we compare the
metered Max to the actual time instead of the desired time.

This removes the dashboard project. The dashboard was an experimental
browser UI for geth which displayed metrics and chain information in
real time. We are removing it because it has marginal utility and nobody
on the team can maintain it.

Removing the dashboard removes a lot of dependency code and shaves
6 MB off the geth binary size.
