Solr LocalParams for Lucene Query Parser [LUCENE-4271]

The Lucene QueryParser should implement Solr's LocalParams syntax directly so that instead of

```Java
_query_:"{!geodist d=10 p=20.5,30.2}"
```

one could directly use

```Java
{!geodist d=10 p=20.5,30.2}

```

Start with the Lucene QueryParser and the linked Solr LocalParams reference to understand the requested syntax. Done means the parser accepts `{!geodist d=10 p=20.5,30.2}` directly rather than requiring it inside `_query_`.
