"doveadm sync/backup" and SSH should use "ssh-agent" if available

I use SSH-AGENT in my system, to cache SSH credentials and avoid typing my key every time I connect to a remoto host.

But "doveadm sync/backup", when one of the ends is SSH accessed, doesn't use the available SSH-AGENT and forces me to type my password.
