Chatty remove script

make remove-all-data.sh more verbose (or at least less quiet)

• remove -f flag in rm command
• remove touch data/postgres/data/.gitkeep as .gitkeep is not deleted by rm -r data/postgres/data/*
• remove data/minio/vol0/.writable-check-*as that is only needed in multi-node mode
• add rm -r data/tomcat/context/*
