When constructing a Deployment (which is a plaintext representation of a Snapshot), ensure that we encrypt secret values. To do so, we introduce a new type `secrets.Manager` which is able to encrypt and decrypt values. In addition, it is able to reflect information about itself that can be stored in the deployment such that we can deserialize the deployment into a snapshot (decrypting the values in the process) without external knowledge about how it was encrypted. The ability to do this is import for allowing stack references to work, since two stacks may not use the same manager (or they will use the same type of manager, but have different state). The state value is stored in plaintext in the deployment, so it **must not** contain sensitive data. A sample manager, which just base64 encodes and decodes strings is provided, as it useful for testing. We will allow it to be varried soon.
