## Description
Add a query to `sqoop.py` (analytics/refinery repo) for periodic extraction of data from the table `wikilambda_zobject_function_join`, to be sent to the data lake. An example query is given by [[ https://gerrit.wikimedia.org/r/c/analytics/refinery/+/736021 | this patch ]].
The table is declared [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/WikiLambda/+/refs/heads/master/sql/ | here ]].
`wikilambda_zobject_function_join` is declared [[ https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/WikiLambda/+/refs/heads/master/sql/ | here ]].
Consider whether to extract everything, or possibly omit some columns from the extraction.
