Add note explaining analysis caching for plugins 

```
Elasticsearch doesn't have any automatic mechanism to share these
components between indexes. If any component is heavy enough to
warrant such sharing then it is the Pugin's responsibility to do
it in their {@link AnalysisProvider} implementation. We recommend
against doing this unless absolutely necessary because it can be
difficult to get the caching right given things like behavior
changes across versions.
```
