[pbs-devel] [PATCH v2 proxmox-backup 2/2] tools-http: Add proxy option for get_string

[Dylan Whyte <d.whyte@proxmox.com>]

Adds a proxy argument to the get_string function, which will use the
proxy connector if it has a value. Also updates calls to the function to
avoid breakages

Signed-off-by: Dylan Whyte <d.whyte@proxmox.com>

I decided to add this in with the fix, although it currently has no
effect. Again, once the situation with the administration config file
is understood, I can get the proxy from that.
