DRILL-7075: Fix debian package issue with control files
Add control file to generate debian package where we have deleted in #1669 PR. We need control file either in static form or dynamic form. The control file gives details about the package and conffiles used when a new version is installed then dpkg knows to ask what do you want to do with differences instead of just replacing file. According to debian packaging rules the control files are must and conffile is optional. Hence to add control file. We also need to add "<exclude>**/control</exclude>" in distribution/pom.xml file. Because without this line "mvn clean install -DskipTests -Drat.skip=false -Dlicense.skip=false" will fail.
