e45c399467 lib/protoparser/prometheus: properly unescape label values in Prometheus exposition format
Unescape only `\n`, `\"` and `\\` sequences as Prometheus does. Other escape sequences shouldn't be unescaped.

2ed721e457 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.

dad8b76a0e 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.

cd87ca303f 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.

1f0e8fdc0d 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.

See https://www.robustperception.io/life-of-a-label for details.
