ParamByPath Nesting

[cmattoon]

Given the following SSM Params, and aws-ssm/aws-param-name: /path/to/db

• /path/to/db/passwd
• /path/to/db/etc/foo
• /path/to/db/etc/passwd

Since the current implementation uses basename, the keys passwd and foo will be set in the Secret, but which passwd seems to be undefined. Also, I feel like the keys should probably be passwd, etc_foo, and etc_passwd, and/or a limit placed on the recursion.
