BytesReference.Helper should never materialize a byte[] array.

The current implementations of BytesReference.Helper.bytesEquals and
bytesHashCode materialize a byte[] when passed an instance that returns `false`
in `hasArray()`. They should instead do a byte-by-byte comparison/hashcode
computation without materializing the array.

Close #5517
[DOCS] Moved the template query documentation into search section
Let ByteArray/BigByteArray.get() indicate whether a byte[] was
materialized.
Fix include_in_all for multi field, to not include multi fields into _all field.

Closes #5522
Set the actual bytes used in circuit breaker back to how it was before loading if the loading wasn't successful.
Added close() calls into catch block, in the event it fails afterLoad will be invoked
