Under high load LC/Scheduler has long response time (30-90 seconds, even more).
Implement RPC timeout and delay.
Created attachment 437530 [details]
This adds increasing timeout to RPC. When the call's time expires it is repeated after delay.
The delay is increasing after failures and decreasing after pass which relieves the stress on server when overloaded, while not causing too big slowdown on minor hick-ups.
The patch tested on beaker with Tier1 tests: see J:11070, J:11080 and J:11084.
beah-0.6.12-1 to be delivered tomorrow was built.
