An option to disable proxy in Deno.CreateHttpClientOptions

[denis-migdal]

Hi,

Sometimes we have a computer behind a proxy, and we want to send queries to localhost.
However, when the http_proxy environment variable is set, such requests are sent to the proxy... (which is also a security issue...).

Could it be possible to add an option to Deno.CreateHttpClientOptions, in order to disable the system's proxy ?

This could be one of the following (I do not know which one would be the best):

Deno.createHttpClient({ proxy: null });
Deno.createHttpClient({ proxy: false });
Deno.createHttpClient({ use_proxy: false });
Deno.createHttpClient({ noproxy: true });
Deno.createHttpClient({ proxy: {url: null} });

Cordially,

This seems reasonable. I think we should support:

Deno.createHttpClient({ proxy: "inherit" }); // default, what we already do when proxy is not set
Deno.createHttpClient({ proxy: "disable" }); // new behaviour being requested
Deno.createHttpClient({ proxy: { url: "..." } }); // existing behaviour, use a different proxy

A PR would be welcome.
