refactor(http): implement shared transport and clients (#1288)

* fix(http): flip to a shared transport and clients

* nice threads

* that is terrible

* fake uri for magnet

* lazy locking

* why bother with r's

* flip magic params to struct

* refactor(http-clients): use separate clients with shared transport

* refactor(http-clients): add missing license header

* refactor(http-clients): defer and fix errors
