[native] Use cnx.system_sql instead of doexec method in syntax_tree_search The latter handles connection issues and tries to reconnect. Method syntax_tree_search appears to be called from quite a few place where it seems useful to be resilient to connection issues (authentication for instance). This reconnection logic appears to have disappeared at some point when working on https://www.cubicweb.org/2919309. Could not find the exact reason though...

RQL logs
========

You can configure the *CubicWeb* instance to keep a log
of the queries executed against your database. To do so,
edit the configuration file of your instance
``.../etc/cubicweb.d/myapp/all-in-one.conf`` and uncomment the
variable ``query-log-file``::

  # web instance query log file
  query-log-file=/tmp/rql-myapp.log
