member.ex audit

[dpslwk]

After 6 years we should remove ex member records
but to keep DB integrity we likely obfuscate the data

need to look carefully at what tables are have already that need cleaning and as we add more this audit will constantly need updating

going to be best to break this down in Entity base files in say app/HMS/Obfuscate/
so when adding a new entity we add a new EntityObfuscate.php file and the command runs uses auto discovery to find them all and call handle/run methods
