Deal with tfa_ data

[mpchadwick]

tfa_ tables also contain encrypted values. from what I was overhearing in Slack they are maybe even double-encrypted? (encrytped vlaue added to JSON then encrypted again). Just creating this issue to track this so this module can offer some solution for re-encrypting these.

@cjnewbs Proposed solution

• Base new command on https://github.com/genecommerce/module-encryption-key-manager/blob/master/Console/ReencryptColumn.php
• Strip out all handling for tables etc, only need --force because we're hardcoding the table and columns
• begin targeting tfa_user_config
• decrypt the value
  • iterate through
    • look at secret and re-encrypt
• reencrypt whole value
• need to display before/afters in CLI in similar format
• Try and keep the output similar
• Try and add a basic test in test.sh
