Os module

[michael-fleming]

updates to Kinesis and Opensearch modules:

Kinesis:

• updated s3 destination to extended s3
• moved s3 configuration block in main.tf

Opensearch:

• updated resource identifiers in data.tf due to race condition (the policies being created referenced resources they were required to be attached to)
• added locals for security group, subnet, and autotune options and used these in the cluster creation

Hey @michael-fleming - the changes you made look great. I think this is ready for testing. Please note that I did not review the Kinesis module changes included in this pull request, just focused on OpenSearch.
