Adds `redshift_cross_region_snapshots` module (#35527)
* add redshift_cross_region_snapshots module, unit tests. * fix errors * use ec2_argument_spec as the basis for the argument spec. fixed metadata_version * follow best practices by naming example tasks. * code review changes * fix linting errors * Update version addedpull/49433/head
