Retrieve info from Azure for Verizon CDN

Log into Azure using the raw api https://login.microsoftonline.com/{}/oauth2/token\ passing required headers to get Oauth token. Then retrieve CDNS ip's from "https://management.azure.com/providers/Microsoft.Cdn/edgenodes?api-version=2023-05-01"

Set login credentials in .env

• Create App in Azure Id

  • Create Client_ID (AppID) and secret for the app to login with

• Create .env file in root of repo

  ## NOT in GIT##
  TENANT_ID="39......-....-....-....-............3"
  # client id / app id
  CLIENT_ID="4.......-....-....-....-...........5"
  # client secret / password for app/client id
  CLIENT_SECRET="F......................................D"
  

High level flow

1. src/req_get_info.rs gets Oauth token from [https://login.microsoftonline.com/{TENANT_ID}/oauth2/token]
2. src/req_get_info.rs then gets Verizon cdn ips from [https://management.azure.com/providers/Microsoft.Cdn/edgenodes?api-version=2023-05-01]
3. src/parse_cdn.rs with serde is used to parse the info
4. we grab all the ipv4 ips and masks, make them uniq and print them in a list that can be used with nginx real_ip module, to identify valid forwarded_for IP's
