Doc note: This adds *hive.spark.use.ts.stats.for.mapjoin* to HiveConf.java, replacing and removing *hive.spark.use.file.size.for.mapjoin* which was added in release 2.3.0 by HIVE-15489.

** [hive.spark.use.file.size.for.mapjoin | https://cwiki.apache.org/#ConfigurationProperties-hive.spark.use.file.size.for.mapjoin]
I won't add a TODOC label because I just took care of the documentation.

> The name {{hive.spark.use.file.size.for.mapjoin}} is confusing. It indicates that HoS uses file size for mapjoin but in fact it still uses (in-memory) data size. We should change it.
