Currently, we do not verify the TLS certificate for API requests external IPAM and DNS integration. This could allow man-in-the-middle attacks, albeit most IPAM infrastructure is on controlled and isolated LANs, so it's not something that should frequently happen; and technically our IPAM integration is still marked as tech-preview, which had its reasons. Enforce verification, and allow users to pass a cert SHA256 fingerprint to ensure a certificates validity if it's not trusted by the system trust store, as it's, e.g., the case for self-signed certs. The code was adapted from the one in pve-apiclient, which we cannot reuse directly as it is only implemented for requests against PVE nodes, not as a generic HTTP client request helper. Add the new dependency `libio-socket-ssl-perl` required to get the verify callback for the TLS certificate used for cert-fingerprint checking.
