add support to set datasource timeout

[alex-berger]

This addition allows setting the data-source HTTP client timeout, to work around situations where the default timeout is to small.

Note, I choose the type int for the timeout as this is what the Grafana code primarily expects, technically string or intstr.IntOrString would also work.
