Title: Garbd does show as empty string in wsrep_incoming_addresses, which leads to glb parse error.

Added sed command to filter starting comma, ending comma, and multiple commas.

echo ",,,,,10.0.20.1:3306,,,,10.0.20.3:3306,10.0.20.8:3306,,,," | sed -e 's/,,*/,/g' -e 's/^,//g' -e 's/,$//g'
10.0.20.1:3306,10.0.20.3:3306,10.0.20.8:3306
