Update HTTPRequest.cs

[Xlinka]

Updated HTTP NODE to use one HTTP CLIENT instead of instantiating a new one for each pulse

I couldn't see why #131 was happening, since I was only reusing the CloudXInterface.SafeHTTPClient, which is the same httpClient that's used in the vanilla GET and POST string nodes. But if changing it to its own httpClient fixes the problem, then I guess it's fine.

Maybe we should add a neosplus safehttp client for neosplus usage?

[Lexevolution]

The only difference between the regular one and the "safe" one is that the "safe" one has a one minute timeout. Which can just be added by putting

client.Timeout = TimeSpan.FromMinutes(1);

directly after this.

Odd

merging since it fixes issue will update if anything else arrises
