Add configuration for tunable dataloss sensitivity
--------------------------------------------------

                 Key: HBASE-2363
                 URL: https://issues.apache.org/jira/browse/HBASE-2363
             Project: Hadoop HBase
          Issue Type: Improvement
    Affects Versions: 0.20.3, 0.21.0
            Reporter: Todd Lipcon


There are many cases in HBase when the process detects that some data is "not quite right".
We often have two choices: (a) throw up our hands and exit, or (b) log a warning and push
through the issue, potentially losing data. I think some users are very sensitive to dataloss
and would prefer that the system become unavailable rather than continue with potentially
lost data. Other users just want the system to stay up, and if they lose a log segment it's
fine.
