Reduce password prompts with macOS KeyChain

Overview

aws-sso now stores data in a single record in the login KeyChain on macOS instead of a custom AWSSSOCli keychain. This has the nice side effect of dramatically reducing the number of password prompts users should experience.

Additionally, we now support limiting History items based on time via the HIstoryMinutes option. By default, roles will disappear from the History tag after 24hrs or once you reach HistoryLimit items- which ever comes first.

Lastly, the console command no longer supports the --use-sts flag as it was superfluous. Users wishing to not use the current AWS credentials in their environment should specify --prompt or the appropriate --arn or --account and --role flags.
