IMPALA-3552: Make incremental stats max serialized size configurable The fix "IMPALA-2648/IMPALA-2664" introduced a conservative limitation on the maximum serialized size of incremental stats. As a side effect, some users with very large tables are experiencing regressions especially when they upgrade impala and the serialized size goes beyond 200MB. To mitigate the issue, the change introduces a new gflag, 'inc_stats_size_limit_bytes' to make the max serialized size configurable, which allows impala users to specify their own maximum serialized size. Default value for inc_stats_size_limit_bytes is 200MB. The change includes TBackendConfig to pass backend configs, set of gflags, to frontend, Catalog and Frontend. This also revamps existing query options to use the TBackendConfig.
