Merge all the rule json metadata into a single file

[april]

Right now, it is extremely hard to figure out the rule order from looking at anything but auth0 directly. My proposal would be to merge everything into a single metadata.json file that would look something like this:

{
  "rules": [
    {
      "filename": "duosecurity.js",
      "enabled": true,
      "name": "Force staff (LDAP) to use MFA"
    },
    {
      "filename": "aai.js",
      "enabled": true,
      "name": "Authentication Assurance Indicator"
    },
    {
      "filename": "AccessRules.js",
      "enabled": true,
      "name": "Access Rules"
    },
    {
      "filename": "default-deny-for-maintenance.js",
      "enabled": false,
      "name": "Deny access to all users if we are in maintenance mode"
    }
  ]
}

Pros of this method:
• Easy to see all the rules in their order at one glance
• No need to set numbers, as the order they appear in the list would set their order in auth0 (the deployment script would increment by 10 for each rule)
• Rules would be stored locally with normal javascript file names, but could be deployed to auth0 with descriptive names instead of names like aai.js
