I wonder if we should examples in these methods about how not to use them when required (basically including examples of custom HTTPS, or at least linking to them)

Motivation and Context
This PR fixes awslabs/aws-sdk-rust#467 which was caused by making the SDK clients use
DynConnectorin #1132.There's a bit of conflict here between smithy-rs and SDK use-cases. Developers using smithy-rs want the flexibility to use static dispatch on the client's connector, but the SDK does not need this. I'm opting to make the SDK use-case easy and convenient, and it should even work for most smithy-rs use-cases. Those who need to use static dispatch will need to manually construct an adapter (for example,
builder.connector(Adapter::builder().build(aws_smithy_client::conns::https()))) if the performance difference is a concern.I considered adding
rustls_staticandnative_tls_staticequivalents for static dispatch, but I thought those might cause confusion.Testing
