[Datasource] Do not send "search" request each time user type to get autocomplete on options

Hi,

First thanks for that awesome plugin https://github.com/grafana/simple-json-datasource it helped me to start writing a plugin for Grafana.

I am developing a separate datasource and I saw that on both on them, when the user types in the gf-form-dropdown to get autocomplete, it sends a “search” request each time the user type something.
As my API is a bit slow, if the user types too much, then requests starts to stack and each time propose completion and it’s a bit of a pain.

Is it possible to send the search request only once when the user click on the dropdown and do the autocomplete on that only search request ?
That way it would reduce the load on the API I am querying.

Many thanks in advance.

I think it’s related to that issue : https://github.com/grafana/grafana/issues/1926
