new plugin request: Veeam backup monitoring using Veeam Backup Enterprise Portal

[joschi99]

It should be nice to monitor Veeam Backup through the Veeam Backup Enterprise Portal, which offers different advantages;

• Rest API: https://helpcenter.veeam.com/docs/backup/em_rest/em_web_api_reference.html?ver=110 Is more powerfull and has more performance as the actual Powershell scripts, which has performance problems
• We can monitor centrally more then 1 Backup Server

It should possible to monitor and discover:

• Veeam Backup Servers
• Veeam Jobs
• Veeam Repositories
• Veeam Nas backup
• Veeam CDP
• Veeam Tasks

We can provide access to Rest API.

If you can provide all curl commands and results it would be really nice
