Custom proxy url for HTTP Request Actions

We're excited to announce the http_proxy_url parameter for HTTP Request Actions, a dedicated attribute of an existing feature that allows you to direct your requests through a specified proxy with ease, providing more control on a per Action basis. We're also keeping the existing HTTP_PROXY environment variable for any who is already using it.

A heads-up for our self-hosted friends: using both the HTTP_PROXY environment variable and http_proxy_url on the same agent will prompt our system to raise an exception, ensuring no HTTP request actions bypass your setup.

Happy automating 🚀
