Shorter target names

[doublemarket]

When an RRD file is in a deep directory, the target name will be long. If we have an option to pick only some directory names or a DS for the target name in the path, that makes graph legend names shorter.

Possible solution : Creating a function like aliasByNode of graphite-web.

Hello, I think that using aliases can be interesting for the future so that we can use the metrics for more complex operations.

Would be nice to have a possibility to provide a custom name for a metric. More information in the same topic: How to override metric name, Aliasing a metric.
