For debug logging we need a shortened string for better readability and
grepping. The standard toString is way too long. I changed toString to a
similar compact form that we had before. adding in the frontend generation id
and type, eg
member-1-datastore-config-fe-1-txn-3
member-1-datastore-operational-fe-1-chn-2-txn-3
