Describe the bug

When the output type is HTTP and after the data is successfully sent over HTTP, https://github.com/akamai/uls/blob/main/bin/modules/UlsOutput.py#L477 exits the method early and does not log the success message in https://github.com/akamai/uls/blob/main/bin/modules/UlsOutput.py#L503. We have setup alerts to notify if a successful message is not seen for 24 hours

To Reproduce
Steps to reproduce the behavior:

1. Run python bin/uls.py --input 'EAA' --feed 'ACCESS' --edgerc '.edgerc' --output 'HTTP' --httpurl 'https://<splunk_or_similar_app>' --httpauthheader '{"Authorization": "Splunk "}' --httpaggregate 1 --loglevel 'DEBUG' --debugloglines 'True' --filter ".'apphost': ''."
2. Notice that "...Data successfully sent via..." message will not be displayed upon successful log transfer

Expected behavior
"...Data successfully sent via..." message should be logged upon successful log transfer
