Mark 'lucene-expression' as 'provided' in pom.xml

We currently pull in the lucene-expression module that is referenced
by lucene-suggest. Yet, we don't make use of this dependency at all
and it pulls in a bunch of unshaded libs like `antlr` and `asm` which
are pretty common in other projects. We should exclude this
dependency since we don't use it at all and it causes problems
when Elasticsearch is used as a node client. (see #4858)

If we mark the dependency as provided it won't be included in the
distribution.

Closes #4859
