Add option to use GET vs POST for seeding.

So far this only has the form field and helper function. This needs work to add the logic for using GET/POST based on this.

Added a commit that handles updating the internal request method; after doing a bit of digging on drupal_http_request it defaults to GET https://api.drupal.org/api/drupal/includes%21common.inc/function/drupal_http_request/7.x — so this change might not be super relevant after the fact.

Without the change:

drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:42:35 +0000] "GET /node/48 HTTP/1.0" 200 11236 "-" "Quant (+http://quantcdn.io)" "-"
drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:42:35 +0000] "GET /node/49 HTTP/1.0" 200 10827 "-" "Quant (+http://quantcdn.io)" "-"

With the change (enable GET)

drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:42:35 +0000] "GET /node/48 HTTP/1.0" 200 11236 "-" "Quant (+http://quantcdn.io)" "-"
drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:42:35 +0000] "GET /node/49 HTTP/1.0" 200 10827 "-" "Quant (+http://quantcdn.io)" "-"

and with the change enable POST

drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:44:31 +0000] "POST /node/25 HTTP/1.0" 200 11589 "-" "Quant (+http://quantcdn.io)" "-"
drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:44:31 +0000] "POST /node/26 HTTP/1.0" 200 12081 "-" "Quant (+http://quantcdn.io)" "-"
drupal7-docker-stack-nginx-1  | 172.23.0.3 - - [07/Jul/2023:00:44:31 +0000] "POST /node/27 HTTP/1.0" 200 11826 "-" "Quant (+http://quantcdn.io)" "-"

This aligns D7 with D8+ so it's a good change though.

Ah, gotcha. I removed the helper function. I'll merge this.

Do we need to update the curl POST logic in quant_api_quant_seed_file?
