Upgrade master to lucene 5.0 snapshot

This has a lot of improvements in lucene, particularly around memory usage, merging, safety, compressed bitsets, etc.

On the elasticsearch side, summary of the larger changes:

    API changes: postings API became a "pull" rather than "push", collector API became per-segment, etc.
    packaging changes: add lucene-backwards-codecs.jar as a dependency.
    improvements to boolean filtering: especially ensuring it will not be slow for SparseBitSet.
    use generic BitSet api in plumbing so that concrete bitset type is an implementation detail.
    use generic BitDocIdSetFilter api for dedicated bitset cache, so there is type safety.
    changes to support atomic commits
    implement Accountable.getChildResources (detailed memory usage API) for fielddata, etc
    change handling of IndexFormatTooOld/New, since they no longer extends CorruptIndexException

Closes #8347.

    Make the and filter use the cost API.

    Lucene 5 ensured that cost() can safely be used, and this will have the benefit
    that the order in which filters are specified is not important anymore (only
    for slow random-access filters in practice).

    Cut over XBooleanFilter to BitDocIdSet.Builder.

    The idea is similar to what happened to Lucene's BooleanFilter.

    Yet XBooleanFilter is a bit more sophisticated and I had to slightly
    change the way it is implemented in order to make it work. The main difference
    with before is that slow filters are now applied lazily, so eg. if you have 3
    MUST clauses, two with a fast iterator and the third with a slow iterator, the
    previous implementation used to apply the fast iterators first and then only
    check the slow filter for bits which were set in the bit set. Now we are
    computing a bit set based on the fast must clauses and then basically returning
    a BitsFilteredDocIdSet.wrap(bitset, slowClause).

    Other than that, BooleanFilter still uses the bitset optimizations when or-ing
    and and-ind filters.

    Another improvement is that BooleanFilter is now aware of the cost API.

    Removed the work around to prevent p/c error when invoking #iterator() twice, because the custom query filter wrapper now doesn't transform the result to a cache doc id set any more.

    I think the transforming to a cachable doc id set in CustomQueryWrappingFilter isn't needed at all, because we use the DocIdSet only once and because of that is just slowed things down.

Discovery: a more lenient wait joinThread when stopping

When a node stops, we cancel any ongoing join process. With #8327, we improved this logic and wait for it to complete before shutting down the node. In our tests we typically shutdown an entire cluster at once, which makes it very likely for nodes to be joining while shutting down. This introduces a race condition where the joinThread.interrupt can happen before the thread starts waiting on pings which causes shutdown logic to be slow. This commits improves by repeatedly trying to stop the thread in smaller waits.

Another side effect of the change is that we are now more likely to ping ourselves while shutting down, we results in an ugly warn level log. We now log all remote exception during pings at a debug level.

Closes #8359

[CORE] Cut over to Path API for file deletion

Today we use the File API for file deletion as well as recursive
directory deletions. This API returns a boolean if operations
are successful while hiding the actual reason why they failed.
The Path API throws and actual exception that might provide better
insights and debug information.

Closes #8366
[TRANSLOG] Translog leaks filehandles if it's corrupted or truncated

If the translog file is corrupted or truncated the stream is never closed
