Update allocation.asciidoc

It's minor, but I've added the percentage representations in brackets as it took me a couple of attempts to figure out I wasn't supposed to be using an actual percentage, eg 80%/90%, but a decimal representation of the value, eg 0.80/0.90.

That should make it a lot clearer for others.

Both notations are supposed to work. Can you please provide us with the command that didn't work so that we can look into what went wrong?

Using sense, updating from 0.99 to 99%;

This is the curl;
PUT /_cluster/settings
{
"transient" : {
"cluster.routing.allocation.disk.watermark.high" : "99%"
}
}

Then setting back to 0.99

I'm running ES 1.1.1 on Ubuntu 12.04, Oracle JRE 1.7.0_u55.

OK, I just understood why I was confused. There is indeed an issue with Elasticsearch 1.1 but this is fixed in current development code and the fix will be part of the upcoming 1.2.0 release. See #5690 for more information.
