[Performance] Improve parsing dates and times

[lucaspouzac]

Actually, io.vertx.httpproxy.impl.ParseUtils use SimpleDateFormat to parse a date.

It would certainly be possible to improve memory consumption, perhaps using another more efficient method (LocalDateTime.parse ?)

Java Flight Recorder during 300s
I observe more than 4% of the memory consumption of my application linked to this analysis.

Screenshot showing 1,3% of memory usage.

Observed with the version 4.5.1 (from quarkus 3.7.0)
