Tries the following:
- Factory to store named sets of standard Session configurations (baseURL, Header, Parameters, Redirects, HTTP proxies)
- All Session objects created share DNS, connection, SSL and cookie cache
- Sessions are configured with a retry policy with backof
- Can invoke verbs (Get, etc) with relative URLs, otherwise same parameters as cpr
- Proxy autodiscovery via libproxy
- proxy connectivity test on session creation
- during request retries optionally try connects w/o proxy
It provides a class cprex::Session utilizing cpr::Session.

Basic use:
cprex::Factory::PrepareSession("ipify", "https://api64.ipify.org");
cprex::Factory::PrepareSession("stat", "https://httpstat.us/");
...
auto ipify = cprex::Factory::CreateSession("ipify");
auto r = ipify.Get("/");
...
auto stat = cprex::Factory::CreateSession("stat");
r = stat.Get("/200");Some parameter:
r = stat.Get("/200", cpr::Parameters {{"sleep", "5000"}});TODOs:
- maybe resolve IP in PrepareSession() and also maybe perform connectivity tests
- Add decorrelation jitter as described here:
