Support multiple keys per secret in AWS Secrets Manager secrets store

[passuied]

Describe the feature

AWS Secrets manager secrets store currently doesn't support multiple keys per secret. This would be a very useful feature.
We can make it backwards compatible by adding a new optional metadata value MultipleKeysPerSecret

The resulting secrets will be outputted as {key} e.g. key1
If the value is NOT a JSON, it would return the secret string as is (existing behavior)
If the metadata value is set to false, it would return the secret string as is (existing behavior)

Release Note

RELEASE NOTE: ADD support for multiple keys per secret for AWS Secrets manager secrets store

@JoshVanL any way to review this PR? It's pretty simple and additive... Not sure why it's closed as Not Planned
