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.
