Fix loading of secrets config file

Add code to allow Dataverse to re-trigger processing of archived log files. Alleviate the need to manually edit the state file and delete the year-month database

Needed for IQSS/dataverse.harvard.edu#3

@stevenwinship, given that you're adding a new flag, can you document it in the README and update the instructions about how to manage state, e.g. in

counter-processor/README.md

Lines 126 to 131 in 4c662cd

	If you wish to completely reprocess and submit a month's data from log files you can:
	1. Manually send a DELETE request to the hub for an id to remove a report.
	2. Remove the state data from the json file for a particular year-month.
	3. Remove the appropriate month's sqlite database from the file system
	4. Reprocess the month. If it's after the month, use *year_month* for the months report you'd like.

Updated the README and also added the DELETE from DataCite to the re-run automation

Looks good. An upgrade to remove the deprecated/now removed yaml.load() call and a new flag to be able to clear state to rerun a month's processing.
