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.

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.

which could lead to samples with zero values stored in the database.
