when using wildcard notation delete all indices might kick in even though its disabled
Enabled the option of configuring plugin types in the settings. This will also help in tests when testing plugin related functionality
no need to optimize on the bool query parser, we already do that in the optimizeQuery method
MinimumNumberShouldMatch inconcistency, closes #2194
Streamline the use of minimum should match to all relevant queries to accept `minimum_should_match`, and allow all relevant queries to accept the advanced "string" based config
Upgrade to netty 3.5.5, closes #2196.
protect a bit more from bogus (not relevant) exceptions when closing a node
Reduce index.shard.recovery.concurrent_streams from 5 to 3 to reduce the load when doing recovery, closes #2199.
the index.shard.recovery.concurrent_streams controls how many streams are opened from a recovery source to a recovery target to transfer index files. Reduce it from 5 to 3 to reduce the load when doing recovery (for example, due to relocation).

Note, recent changes in network buffering will mean that recovery will progress considerably faster, so this change will not affect recovery times.

fix wrong check on close
Bulk UDP, closes #2201
A Bulk UDP service is a service listening over UDP for bulk format requests. The idea is to provide a low latency UDP service that allows to easily index data that is not of critical nature.

The Bulk UDP service is disabled by default, but can be enabled by setting `bulk.udp.enabled` to `true`.

The bulk UDP service performs intenral bulk aggregation of the data and then flushes it based on several parametres:

* `bulk.udp.bulk_actions`: The number of actions to flush a bulk after, defaults to `1000`.
* `bulk.udp.bulk_size`: The size of the current bulk request to flush the request once exceeded, defaults to `5mb`.
* `bulk.udp.flush_interval`: An interval after which the current request is flushed, regarldess of the above limits. Defaults to `5s`.
* `bulk.udp.concurrent_requests`: The number on max in flight bulk requests allowed. Defaults to `4`.

The network settings allowed are:

* `bulk.udp.host`: The host to bind to, defualts to `network.host` which defaults to any.
* `bulk.udp.port`: The port to use, defaults to `9700-9800`.

Here is an example of how it can be used:

    > cat bulk.txt
    { "index" : { "_index" : "test", "_type" : "type1" } }
    { "field1" : "value1" }
    { "index" : { "_index" : "test", "_type" : "type1" } }
    { "field1" : "value1" }

    > cat bulk.txt | nc -w 0 -u localhost 9700
ignore cancelled key exception as well
add a lock not allowing connecting to nodes while shutting down
Local node master listener

* Fixed an issue where dynamic update to minimum_master_nodes settings would not take immediate effect
* Added LocalNodeMasterListener support to the ClusterService. Enables listening to when the local node becomes/stopped being a master
Fixed issue #2197
allow to register custom state associated with cluster state
0.19.9 no longer supports /_all/_status, closes #2205.
- Explain api opens 2 engine searchers, but closes only 1 engine searcher. Closes #2206
Add ignore_indices option for search, multisearch, count and other Broadcast request. #2209
