Infinite reconnection tries if server not running

[Georg Semmler]

Using a current rasnet build the client(for example rasql) is trying to reconnect forever if the server is not running.

rasql -q "select r from RAS_COLLECTIONNAMES as r" —out string
/usr/local/rasdaman/bin/rasql: rasdaman query tool v1.0, rasdaman v9.1.0-g1198015 — generated on 04.11.2015 11:21:56.

I have the same issue. start_rasdaman.sh and stop_rasdaman.sh should be idempotent in my opinion.
@Alex Can you check this?

[Alex Toader]

I will provide a fix that will abort the connection request after a fixed number of unsuccessful attempts.
I left the default behavior because it gave the user more power on deciding when to give up on connecting to a service.
