Connection Pooling is Disabled by Default for the Hyper Implementation

[mrd0ll4r]

Hello,

by default, the hyper backend disables connection pooling here. This is suboptimal for two reasons:

1. Performance: Performing multiple requests with the same client will open a new connection for each request, which is slow and wasteful.
2. Long-running programs using the same client with many requests exhaust the port space of the host. This manifests in errors like this

   hyper client error `error trying to connect: tcp connect error: Cannot assign requested address (os error 99)`

Alternatively, I'm looking at using the actix client, but it's not obvious how to enable rustls here.
