a906b3862f lib/protoparser/prometheus: properly parse OpenMetrics timestamps
OpenMetrics timestamps are floating-point numbers, that represent Unix timestamp in seconds.
This differs from Prometheus exposition format, where timestamps are integer numbers representing Unix timestamp in milliseconds.

b7f4fc6e0d lib/protoparser/prometheus: properly parse metrics with exemplars
Examplars have been introduced in OpenMetrics - see https://github.com/OpenObservability/OpenMetrics/blob/master/OpenMetrics.md#exemplars-1
Previously VictoriaMetrics couldn't parse the following metric

    foo{bar="baz"} 123 # exemplar here

This commit fixes this. Note that VictoriaMetrics ignores the exemplar as for now.

d8183c3124 lib/protoparser: report more errors for incorrect timestamps and/or values
Previously certain errors in timestamps and/or values could be silently skipped,
which could lead to samples with zero values stored in the database.

d5dddb0953 all: use %w instead of %s for wrapping errors in fmt.Errorf
This will simplify examining the returned errors such as httpserver.ErrorWithStatusCode .

69004a5f67 lib/promscrape: fix tests after the commit 658a8742ac
The original commit copies `__address__` label to `instance` label when generating per-target labels as Prometheus does.
