numeric dataplane frame types

[yesoreyeram]

This PR helps to add proper data frame types when the data frame is comply with numeric-wide/numeric-long data frame types.

This will help to handle the scenarios where these result types will be handled properly in alerts, recorded queries, server side expressions etc.

How to test

Before changes

• Run grafana enterprise version with recorded queries setup
• Open explore and execute the default json backend url query
• Try setting up an recorded query out of it and you will see an error like this

After changes

• Same query should produce valid recorded query results as shown below

May want to check for absence of labels as well.

Infinity doesn't make use of labels. So we are good to go here.

If we are doing this is outside of infinity, definitely consider this.
