Jim Ferenczi fb710cc62b Remove the query builder serialization from QueryShardException message ()
QueryBuilders that throw exceptions on shards when building the Lucene query
returns the full serialization of the query builder in the exception message.
For large queries that fails to execute due to the max boolean clause, this means
that we keep a reference of these big messages for every shard that participate
in the request. In order to limit the memory needed to hold these query shard
exceptions in the coordinating node, this change removes the query builder
serialization from the shard exception. The query is known by the user so
there should be no need to repeat it on every shard exception. We could also
omit the entire stack trace for known bad request exception but it would deserve
a separate issue/pr.
