Expand the Options for storing the sensitive parameters to include binary secrets and SSM Parameter Store

**Is your feature request related to a problem? Please describe.**
Currently sensitive configuration data must be stored in AWS Secrets Manager secrets, however for some customers using SSM Parameter Store may be sufficient (since they do not need cross account/cross region support) and wish to reduce the operating cost of the SSOSync deployment.

**Describe the solution you'd like**
Add detection for and support of SSM parameter store secrets and binary secrets in Secrets Manager.

**Additional context**
Requests originally raised under the following issues:
- [SSOSync fails to get binary secrets #130](https://github.com/awslabs/ssosync/issues/130)
- [Allow use of Systems Manager Parameters instead of Secrets Manager Secrets #93](https://github.com/awslabs/ssosync/issues/93)

Start by reviewing the existing AWS Secrets Manager handling and the linked issues #130 and #93. The work is complete when SSM Parameter Store values and binary Secrets Manager secrets are detected and supported by SSOSync.
