[PATCH pve-mamager v3 0/3] fix #8031: Write APT proxy config on http_proxy change

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

Goal of this patch series is to update the http_proxy config
across the whole cluster immideately after a config change
and independently of the use of PVE tooling to trigger
a database update.

To allow reuse of the same code this patch series factors out
the relevant function inside the APT part of the API and reuses
the function on change of the http_proxy variable in the Cluster API.

This version also moves from trying to update the local file across
all nodes after a change to updating one file in the pmxcfs and
pointing all nodes to that file via a symlink.

Fixes: https://bugzilla.proxmox.com/show_bug.cgi?id=8031

Thanks for the reviews of v2 @e.huhsovitz and @m.sandoval

Changes from v2:
 * added symlink logic to update call
 * adapted update function to only write on change
 * moved update into datacenter.cfg lock phase
