[PATCH pve-manager v3] api: sdn: fix trailing slashes in delete requests

[David Riley <d.riley@proxmox.com>]

Fixes delete request containing double slashes (//), resulting in a
URI like `/sdn/dns//<dns>`. Although this gets normalized on the
server, a strict firewall/proxy might cause problems.

According to RFC 2396, a path may only consist of a
single slash [0].

Notes:
    v3:
    * Fix commit message to reflect the change as "removing trailing
      slash" rather than "fixing double slash".
    * Add technical context regarding RFC 2396
    * Add Suggested-by tag for Nicolas Frey.
    
    v2:
    * Fix trailing slashes in ControllerView and IpamView to address the
      same behavior across the SDN views
