Update HTTP, libcurl, openssl

[AiraYumi]

Are there plans to upgrade from http/1.1 to http/2 and to update libcurl and openssl?

There may not be any particular reason to update, but there is no reason to stick with unsupported libraries or old technology.

I think it needs to be updated to a better alternative.

Paging @monty-linden - this seems like it's up your alley.

Not necessarily these days. But we have a ton of plans including GHIs, Jiras, gdocs, and wikis and it all begins with some infra changes and prioritization.
