Deactivate SQL checks in Codacy

[solth]

At the moment, Codacy checks the syntax of SQL files using SQLint. SQLint only supports "ANSI SQL" syntax:

At this stage, SQLint checks SQL against the ANSI syntax, and uses the PostgreSQL SQL parser to achieve this. SQLint does not have support for non-standard SQL variants (e.g. MySQL), but contributions are welcome.

(see https://github.com/purcell/sqlint , "About").

This leads to SQL statements that are perfectly fine in our environment to be marked as syntax errors by Codacy:

Since this imposes unnecessary constraints on our development I would propose to deactive the SQL checks in Codacy until SQLint supports checking the syntax of the SQL extensions we use.
@Kathrin-Huber , @henning-gerhardt , @matthias-ronge : what do you think?

If that's not just a configuration problem (i.e., we would have to explicitly state that, for example, the syntax accepted by MariaDB is considered valid) then I'm for it. I have never understood these "mistakes".
