Grafana: Variables: Adds substitution regex

Using Grafana v3.1.0, I would like to be able to do a substitution regex in a template, instead of just a match.

For example, if my glob matches the value "abcdef" I would like to use the regex "s/bcd/xyz/" and have the value transformed to "axyzef".

+1 Very useful for transforming some cryptic/to_technical values (e.g: ["ofh","nofh"]) to values that some uneducated user can understand (e.g: ["Office Hours","Non Office Hours"])

+1 Very useful for mapping a variable obtained from one data source query (cloudwatch for ex) to query another data source (graphite)

I think this would be a great addition.
