feat(LinuxParameters): Add LinuxParameters prop and CfnOutput for sns topic

[oielbanna]

• LinuxParameters is needed because it cannot be modified after creation of the container
• CfnOutput is useful in case we need to reference one watchbot stack from another

Both are needed for this PR https://github.com/mapbox/mapbox-places/pull/2116

Testing

I created a beta version and released it to test in mapbox-places watchbot in this PR https://github.com/mapbox/mapbox-places/pull/2116
