qemu: use shorter socket file names to reduce the chance of hitting the max path length

qemu: reduce monitor socket path (#13971) The QEMU driver can take an optional `graceful_shutdown` configuration which will create a Unix socket to send ACPI shutdown signal to the VM. Unix sockets have a hard length limit and the driver implementation assumed that QEMU versions 2.10.1 were able to handle longer paths. This is not correct, the linked QEMU fix only changed the behaviour from silently truncating longer socket paths to throwing an error. By validating the socket path before starting the QEMU machine we can provide users a more actionable and meaningful error message, and by using a shorter socket file name we leave a bit more room for user-defined values in the path, such as the task name. The maximum length allowed is also platform-dependant, so validation needs to be different for each OS. 2022-08-04 16:10:35 +00:00			```release-note:improvement
