John Baldwin 5b51147399 ctld: Permit simpler syntax for target LUNs in UCL 
Allow the LUN number to be specified as the key for a LUN instead
of requiring it as a "number" field.  If a key is used, permit
a simple string value to be used for non-anymous LUNs.  This permits
replacing:

	lun = [
		{ number = 0, name = zvol_lun },
		{
			number = 1
			backend = ramdisk
			size = 1GB
		}
	]

with:

	lun = {
		0 = zvol_lun
		1 {
			backend = ramdisk
			size = 1GB
		}
	}
