Review comment:
In the HTTPApiConfig class, it validates this field and converts to
lowercase. The plugin accepts only `get` and `post` requests. If the field is
`null` or some other unsupported method, the plugin falls back to `get`.

> Storage Plugin for Generic HTTP REST API
> ----------------------------------------
>
> Key: DRILL-7437
> URL: https://issues.apache.org/jira/browse/DRILL-7437
> Project: Apache Drill
> Issue Type: New Feature
> Reporter: Charles Givre
> Assignee: Charles Givre
> Priority: Minor
> Fix For: Future
>
>
> In many data analytic situations there is a need to obtain reference data
> which is volatile or hosted on a service with a REST API.
> For instance, consider the case of a financial dataset which you want to run
> a currency conversion. Or in the security arena, an organization might have
> a service that returns network information about an IT asset. The goal being
> to enable Drill to quickly incorporate external data that is only accessible
> via REST API.
> This plugin is not intended to be a substitute for dedicated storage plugins
> with systems that use a REST API, such as Apache Solr or ElasticSearch.
> This plugin is based on several projects that were posted on github but never
> completed or submitted to Drill. Posted here for attribution:
