Rename a series with a custom template

[miton18]

TSL already have .renameBy() function which allow us to rename a series with its labels.

For some use case, it could be interesting have template the name with a very custom string.

Can we extend .renameBy() function with the following behaviour ?

select('os.cpu').renameBy('${this.labels.hostname} (${this.labels.datacenter})' )
// produce a series named: "1.server.front (GRA)"
