[CLI] search option

Each time we run a unique hash is created so we have no way to tell if a particular tag has been published yet. Being able to consistently publish every tag for a release means that we need to be able to recover from a failure in the process.

If we have a search option (that can have a time element to it to limit the scope of search), we can search and check for a transaction. If it already exists, then we know we can skip publishing that particular tag. This would let us retry as needed without creating unnecessary tag+hash while attempting.
