[pbs-devel] [PATCH proxmox] fix #4162: sys: added `auto-submitted` header to email body

[Gabriel Goller]

`Auto-Submitted` is defined in the rfc 5436 [1] and describes how
an automatic response (f.e. ooo replies, etc.) should behave on the
emails. When using `Auto-Submitted: auto-generated` (or any value
other than `none`) automatic replies won't be triggered.
