Datasource variables

Grafana allow custom fields in datasource configuration

You can easily add strings and numbers.

Since WarpScript doesn't easily manage multi-line strings, you (actually) can't have multi-line strings in a variable.

If you choose foo as variable name in datasource configuration, this variable is availables as $foo on your WarpScript query

You can also store macros in variables, make sure the content of the variable starts with <% and ends with %>
