[sr-dev] [kamailio/kamailio] kamctl - maintenance for dbtextdb.py tool (#2469)

**kamctl** include a python tool that is parsing SQL statements to do operations over the **db_text** files, for the common db operations (e.g., insert, delete). It is located at:

* https://github.com/kamailio/kamailio/tree/master/utils/kamctl/dbtextdb

The tool was contributed long time ago and not kept up to date, being known not to work with Python3 (e.g., #2464).

This issue is created to see if someone has the interest to pick up the maintenance of this tool, if not it will be removed from kamctl.

Note that db_text works with text files, so it is not necessary to have a tool for managing the content of these files, they can be simply updated with any text editor.
