Add span within/containing queries.

Expose new span queries from https://issues.apache.org/jira/browse/LUCENE-6083

Within returns matches from 'little' that are enclosed inside of a match from 'big'.
Containing returns matches from 'big' that enclose matches from 'little'.

=== Span Containing Query
Returns matches which enclose another span query. The span within
query maps to Lucene `SpanContainingQuery`. Here is an example:
[source,js]
--------------------------------------------------
{
"span_containing" : {
"little" : {
"span_term" : { "field1" : "foo" }
},
"big" : {
"span_near" : {
"clauses" : [
{ "span_term" : { "field1" : "bar" } },
{ "span_term" : { "field1" : "baz" } }
],
"slop" : 5,
"in_order" : true
}
}
}
}
--------------------------------------------------
The `big` and `little` clauses can be any span type query. Matching
spans from `big` that contain matches from `little` are returned.
