Boaz Leskes 102e7adfad Recovery: be more resilient to partial network partitions
This commits adds a test that simulate disconnecting nodes and dropping requests during the various stages of recovery and solves all the issues that were raised by it. In short:

1) On going recoveries will be scheduled for retry upon network disconnect. The default retry period is 5s (cross node connections are checked every 10s by default).
2) Sometimes the disconnect happens after the target engine has started (but the shard is still in recovery). For simplicity, I opted to restart the recovery from scratch (where little to no files will be copied again, because there were just synced).
3) To protected against dropped requests, a Recovery Monitor was added that fails a recovery if no progress has been made in the last 30m (by default), which is equivalent to the long time outs we use in recovery requests.
4) When a shard fails on a node, we try to assign it to another node. If no such node is available, the shard will remain unassigned, causing the target node to clean any in memory state for it (files on disk remain). At the moment the shard will remain unassigned until another cluster state change happens, which will re-assigned it to the node in question but if no such change happens the shard will remain stuck at unassigned. The commits adds an extra delayed reroute in such cases to make sure the shard will be reassinged
5) Moved all recovery related settings to the RecoverySettings.

Simon Willnauer d2277d70ff [ENGINE] Simplify Engine construction and ref counting
Today the internal engine closes itself it the engine hits an exception
it can not recover from. This complicates a lot of refcounting issues
if such an exception happens during engine creation. This commit
only markes the engine as failed and let the user close it once the exception
bubbles up. Additionally it rolls back the indexwriter to prevent any changes after
the engine is failed.

Looks like the existence of default timestamp is not checked before use. The next line also has the same issue -- uses of default timestamp without checked to see if it's not null.

To reproduce:

```
$ curl -XPUT localhost:9200/twitter2

$ curl -XPUT localhost:9200/twitter2/tweet/_mapping -d '{
     "tweet" : {
         "_timestamp" : {
             "enabled" : true,
             "default" : null
         }
     }
}'

$ curl -XPUT localhost:9200/twitter2/tweet/_mapping -d '{
     "tweet" : {
         "_timestamp" : {
             "enabled" : true,
             "default" : null
         },
         "properties": {
             "user": {"type": "string"}
         }
     }
}'
```

Closes #9204.

Ryan Ernst 060f963a8e Mappings: Remove allow_type_wrapper setting
Before Elasticsearch 1.0, the type was allowed to be passed as the root
element when uploading a document.  However, this was ambiguous if the
mappings also contained a field with the same name as the type.  The
behavior was changed in 1.0 to not allow this, but a setting was added
for backwards compatibility.  This change removes the setting for 2.0.

Martijn van Groningen ca4f27f40e Core: Added `_shards` header to all write responses.
The header indicates to how many shard copies (primary and replicas shards) a write was supposed to go to, to how many
shard copies to write succeeded and potentially captures shard failures if writing into a replica shard fails.

For async writes it also includes the number of shards a write is still pending.

Simon Willnauer 959e3ca9da [CORE] Fold engine into IndexShard
This commit removes most of the Engine abstractions and removes
Engine exposure via dependency injection. It also removes the Holder
abstraction and makes the engine itself start at constrcution time.
It removes the start method from the engine entire which means no engine
instances exists until it's started. There is also no way to stop the
engine to restart, it needs to be an entire new Engine

Martijn van Groningen c94d056454 Fixed a bug that was caused by specifying routing on a multi percolate request causing an ArrayIndexOutOfBoundsException.
The multi percolate shard responses are collected in an atomic array which uses the shard id is used as index, but the number of shards the multi percolate request was meant to go to was used as size of this array instead the total number of shards an index has. This caused the exception when routing was used.

Simon Willnauer 7ec8973fbc [CORE] Delete shard content under lock
Once we delete the the index on a node we are closing all resources
and subsequently need to delete all shards contents from disk. Yet
this happens today under a lock (the shard lock) that needs to be
acquried in order to execute any operation on the shards data
path. We try to delete all the index meta-data once we acquired
all the shard lock but this operation can run into a timeout which causes
the index to remain on disk. Further, all shard data will be left on
disk if the timeout is reached.

This commit removes all the shards data just before the shard lock
is release as the last operation on a shard that belongs to a deleted
index.

Adrien Grand bc86796592 Core: Remove terms filter cache.
This is our only cache which is not 'exact' and might allow for stalled results.
Additionally, a similar cache that we have and needs to perform lookups in other
indices in order to run queries is the script index, and for this index we rely
on the filesystem cache, so we should probably do the same with terms filters
lookups.

Simon Willnauer 236e2491b4 [ALLOCATION] Remove primary balance factor
The `cluster.routing.allocation.balance.primary` setting has caused
a lot of confusion in the past while it has very little benefit form a
shard allocatioon point of view. Users tend to modify this value to
evently distribute primaries across the nodes which is dangerous since
a prmiary flag on it's own can trigger relocations. The primary flag for a shard
is should not have any impact on cluster performance unless the high level feature
suffereing from primary hotspots is buggy. Yet, this setting was intended to be a
tie-breaker which is not necessary anymore since the algorithm is deterministic.

This commit removes this setting entriely.

    when the lucene checksum is there, we always use it.

Simon Willnauer 4900f52619 [ALLOCATION] Weight deltas must be absolute deltas

Adrien Grand 90f98579a2 Upgrade to Lucene 5.0.0-snapshot-1649544.
A couple of changes that triggerred a refactoring in Elasticsearch:

 - LUCENE-6148: Accountable.getChildResources returns a collection instead of
   a list.

 - LUCENE-6121: CachingTokenFilter now propagates reset(), as a result
   SimpleQueryParser.newPossiblyAnalyzedQuery has been fixed to not reset both
   the underlying stream and the wrapper (otherwise lucene would barf because of
   a doubl reset).

 - LUCENE-6119: The auto-throttle issue changed a couple of method
   names/parameters. It also made
   `UpdateSettingsTests.testUpdateMergeMaxThreadCount` dead slow so I muted this
   test until we clea up merge throttling to use LUCENE-6119.
