Upgrader (Apache Accumulo Master Server 2.0.1 API)

All Known Implementing Classes:

Upgrader8to9
```
public interface Upgrader
```
The purpose of this interface is to allow per version upgrade implementations to be created. Keeping the code for upgrading each version separate makes it easier to maintain and understand the upgrade code over time.
Upgrade operations should be idempotent. For failure cases upgrade operations may partially complete and then be run again later.
