[PATCH qemu-server 2/2] config: document default balloon behavior

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

The behavior for this key is the following:
- balloning=0: Disabled
- Not defined in the config: Enabled
- balloning=N: Enabled, and target memory set to N MiB

Instead of special-casing balloning=1 (or turning it into a property
string) to enable the drive without setting a target memory size, we
simply document the current behavior better.
