feat: mssql database support

[nextchamp-saqib]

Setting up odbc for MSSQL database connection

1. Install FreeTDS:

   # on mac
   brew install freetds
   
   # on linux
   sudo apt install unixodbc-dev unixodbc freetds-bin freetds-dev

2. Find the driver location:

   tsql -C | grep "freetds.conf directory" | awk '{print $NF}' | sed 's/etc/lib\/libtdsodbc.so/'

3. Copy the driver location (eg. /opt/homebrew/lib/libtdsodbc.so) and put it in the site_config.json under mssql_odbc_driver key. Example:

   {
    "mssql_odbc_driver": "/opt/homebrew/lib/libtdsodbc.so"
   }

4. Add a MSSQL data source and check if it works

I was working on it too, same way.
Thanks for that @nextchamp-saqib !

Hi @git-avc

I didn't merge this because I wasn't able to test with a MSSQL database. Let me know if you have any MSSQL instance to test with.

[git-avc]

Hi @nextchamp-saqib ... Yeah, I've tested with your branch, but found some issues with dependencies at connection. Need to install 'ibis-framework[mssql]' package
Tried this but still not working, I'm trying to fix it.

Got it ... ibis mssql needs ODBC SQL Server driver installed on host. So we have to specify driver as argument on connection string (for example ... "ODBC Driver 17 for SQL Server"). IMHO it should be added to Datasource doctype ...

Done here ...
#351

Used generic driver field. Maybe usable for other connectors.
