Parameter to specify which samconfig.toml to use

[milesgranger]

Describe your idea/feature/enhancement

To my understanding, sam deploy does not presently accept a --sam-config type parameter to specify which config to use.

This seems beneficial in cases where one has dev/test/production specific config files for sam

Proposal

Add the possibility to do something like sam deploy --config samconfig-prod.toml

I'd be happy to submit a PR if this seems reasonable and if I could get a short pointer on where to start. 👍
