[PATCH pve-mamager v4 1/3] api: apt: factor out writing the APT proxy config

[Jonas Theisen <j.theisen@proxmox.com>]

Move writing the APT proxy config out of the update_database
endpoint into its own function, so that it can also be called when
the datacenter http_proxy option is changed.

The function takes the already parsed datacenter config, so callers
holding the datacenter.cfg lock can pass their updated copy.
