Investigate a workaround for apps using dot as catalog separator

[bpintea]

ODBC offers an info type allowing the client application to query the driver on what catalog separator to use. ES uses : with the . having a special semantic with JSON (nested) docs.
Nevertheless, some applications either don't bother making the proper info call (ex. Alteryx) or disregard the response if they do (ex Crystal Reports).

A workaround could consist of:

• no longer advertising support for catalogs; and/or
• rewrite the query to correct the use of the wrong character.
