when displaying help information on elasticsearch deprecation log is misleading about its location

[majormoses]

This makes the assumption that the cluster name has not been changed from the default of elasticsearch. I had to spend some time convincing a developer and had to go to the source to confirm this is no indication of the actual filename and is just the default location.

elasticsearch-migration/_site/index.html

Lines 148 to 151 in 3f3f2d4

	<p>
	Deprecation logs can be found in the logs directory, in the
	file named <code>elasticsearch_deprecation.log</code>
	</p>

I think we should either enhance the verbiage to say something like this:

Deprecation logs can be found in the logs directory, in the file named `$CLUSTERNAME_deprecation.log`

Or even better would be to actually just return the value from the es query as you already have this info anyways. For example:

$ curl -s -S $REDACTED:9200/_cluster/state | jq .cluster_name
"es-app"
$ curl -s -S $REDACTED:9200 | jq .cluster_name
"es-app"

This could be javascriptified I am sure but I just wanted to see what peoples thoughts were on this before spending time hacking javascript which I don't really touch front end code so I am sure it would horrify most.

Good point @majormoses. That said, this migration tool is unlikely to see another release now, so it is probably not worth fixing at this point.
