petascope should set up rasql connection once
|Reported by:||dmisev||Owned by:||bphamhuu|
As ticket #1499 demonstrates (especially notice my comment with the measurements, setting up the connection to rasql is pretty expensive (up to 2 seconds in total!). Starting and committing transactions is fast otherwise.
Petascope seems to repeat the setup for every query (RasUtil.executeRasqlQuery), this needs be fixed as soon as possible so that it's done only once when petascope is started.
