Add insecure flag http request table

[bob-bot]

Closes #106

Tested with the following:

Default behavior is insecure = false

select
  url,
  method,
  response_status_code,
  response_error,
  response_body
from
  net_http_request
where
  url = 'https://self-signed.badssl.com';

Same results as:

select
  url,
  method,
  response_status_code,
  response_error,
  response_body
from
  net_http_request
where
  url = 'https://self-signed.badssl.com'
  and insecure = false;

Shows it working with the insecure = true

select
  url,
  method,
  response_status_code,
  response_error,
  response_body
from
  net_http_request
where
  url = 'https://self-signed.badssl.com'
  and insecure = true;
