No Log Info when aca-py fails to create revocation files in the tails server

Issue: Currently, there's no log info in the tails server when aca-py fails to create/upload revocation files, the only information one can get is from the aca-py POST API (/credential-definitions) response for creating a credential definition such that 500: Tails file for rev reg MtSBSkitb28PSoCj9EpSDs:4:MtSBSkitb28PSoCj9EpSDs:3:CL:61850:default:CL_ACCUM:e3b761f5-1218-44bd-8612-0727e777f72d failed to upload: Exceeded maximum put attempts

Lacking the log info in the tails server is hard to determine what's wrong when revocation files failed to be created/uploaded.
