IMPALA-3552: make incremental stats max serialized size configurable

The fix fox "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 upgrading.

To mitigate the issue, the change introduces a new gflag,
'inc_stat_max_size' to make the max serialized size configurable,
which allows impala users to specify their own maximum serialized
size. Default value for inc_stat_max_size is 200MB.

The change also includes TBackendConfig to pass backend config
to frontend.
