Issue:
Typo fix in crate generation README example
https://github.com/rusoto/rusoto/blob/master/service_crategen/README.md has a section for generating a single or set of services with the `-s` flag. The example says `cargo run -- generate -c ./services.json -o ../rusoto/services -s s3 -s ec2` but we're still using `nightly` for crate generation until https://github.com/rusoto/rusoto/pull/1204 lands.

The `cargo run -- generate -c ./services.json -o ../rusoto/services -s s3 -s ec2` line should be changed to `cargo +nightly run -- generate -c ./services.json -o ../rusoto/services -s s3 -s ec2`. The addition of `+nightly` makes the command work even if the default `rustc` version in use is `stable` or `beta`.
