Doc note:  *hive.enable.semijoin.conversion* needs to be documented in the wiki 
for release 2.2.0.

* [Configuration Properties -- Query and DDL Execution | 
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]

Added a TODOC2.2 label.

Edit (16/Feb/17):  HIVE-15894 changes the parameter name from 
*hive.enable.semijoin.conversion* to *hive.optimize.semijoin.conversion*, also 
in release 2.2.0.

We can use CALCITE-1495 for changes in this rule. _auto_sortmerge_join_2.q_ is 
a flaky test. It fails intermittently even locally. Its a poorly written test 
since it depends on memory of system. 

By the way, I also added the flag {{hive.enable.semijoin.conversion}} for the 
rule. 
Pushed to master.
