DataSealerKeyStrategy (java-support 8.0.0 API)

All Known Implementing Classes:

BasicKeystoreKeyStrategy, ScriptedKeyStrategy
```
public interface DataSealerKeyStrategy
```
Interface for acquiring secret keys on behalf of the DataSealer class, this principally abstracts methods of handling key versioning moreso than actual access to keys, by optimizing access to keys in accordance with the manner in which key rollover is handled.
Implementations are expected to guarantee good performance for access to a current "default" key, and may offer less performance on access to non-default keys.
