This is a rewrite of BUGGIFY function/macros. Seems the performance
improved a lot during the simulation, e.g.
fdbserver -r simulation -b on -f ../CycleTest.toml -s 99438

I expected the improvement but did not expect a ~13% improvement.
CC sets a version to int_max in ClientDBInfo indicating a refresh, however,
proxy server would reject this version for the error of future_version.
This change fixes this issue by not sending int_max, instead maintaining a
lastKnown in memory and send it to grvproxy to get latest globalconfig.
this change also fixes some java tests that were used to test the fix
In the current code, errors are retried in getConsistentReadVersion, so it's
possible that the client has cancelled the GRV request, but readVersionBatcher
continue retrying, which can lead to many clients DDoS GRV proxies, especially
when the database has become unavailable for a while and clients are issuing
many GRV requests.
