[3599] Fixed issues with the kea-admin script portability.

The following issues causing failures on the FreeBSD were corrected:
- Don't use sed to replace tabulations from the returned kea version.
Instead the CONCAT mysql function is used.
- Replace &>dev/null with the >/dev/null 2>&1

Additional changes:
- Added a new line before printing existing tables in the mysql.
- Added .gitignore for new files.
