Lee Hinman e53a43800e Add `explain` flag support to the reroute API
By specifying the `explain` flag, an explanation for the reason a
command can or cannot be executed is returned. No allocation commands
are actually performed.

Returns a response similar to:

{
  "state": {...cluster state...},
  "acknowledged": true,
  "explanations" : [ {
    "command" : "cancel",
      "parameters" : {
        "index" : "decide",
        "shard" : 0,
        "node" : "IvpoKRdtRiGrQ_WKtt4_4w",
        "allow_primary" : false
      },
      "decisions" : [ {
        "decider" : "cancel_allocation_command",
        "decision" : "YES",
        "explanation" : "..."
        } ]
     }, {
      "command" : "move",
      "parameters" : {
        "index" : "decide",
        "shard" : 0,
        "from_node" : "IvpoKRdtRiGrQ_WKtt4_4w",
        "to_node" : "IvpoKRdtRiGrQ_WKtt4_4w"
       },
       "decisions" : [ {
         "decider" : "same_shard",
         "decision" : "NO",
         "explanation" : "shard cannot be allocated on same node [IvpoKRdtRiGrQ_WKtt4_4w] it already exists on"
       },
       etc
       ]
  }]
}

also removes AllocationExplanation from cluster state

Alexander Reelsen b02e6dc996 Migrating NodesInfo API to use plugins instead of singular plugin
In order to be consistent (and because in 1.0 we switched from
parameter driven information to specifzing the metrics as part of the URI)
this patch moves from 'plugin' to 'plugins' in the Nodes Info API.

Martijn van Groningen e6f83248a2 Deprecated disable allocation decider which has the following options:
`allocation.disable_new_allocation`, `allocation.disable_allocation`, `allocation.disable_replica_allocation`,
in favour for the enable allocation decider which has a single option `allocation.enable` wich can be set to the following values:
`none`, `new_primaries`, `primaries` and `all` (default).

Alexander Reelsen ad50afbec8 Simplify usage of nodes info API
Important: This breaks backwards compatibility with 0.90

* Removed endpoints: /_cluster/nodes, /_cluster/nodes/nodeId1,nodeId2
* Disallow usage of parameters, but make required metrics part of URI
* Changed NodesInfoRequest to return everything by default
* Fixed NPE in NodesInfoResponse

Alexander Reelsen 6ef6bb993c Cluster state API: Improved consistency
Instead of specifying what kind of data should be filtered, this commit
streamlines the API to actually specify, what kind of data should be displayed.
This makes its behaviour similar to the other requests, like NodeIndicesStats.

A small feature has been added as well: If you specify an index to select on, not
only the metadata, but also the routing tables are filtered by index in order
to prevent too big cluster states to be returned.

Also the CAT apis have been changed to only return the wanted data in order to keep
network traffic as small as needed.

Tests for the cluster state API filtering have been added as well.

Note: This change breaks backwards compatibility with 0.90!

Alexander Reelsen bb275166f1 Simplify nodes stats API
First, this breaks backwards compatibility!

* Removed /_cluster/nodes/stats endpoint
* Excpect the stats types not as parameters, but as part of the URL
* Returning all indices stats by default, returning all nodes stats by default
* Supporting groups & types in nodes stats now as well
* Updated documentation & tests accordingly
* Allow level parameter for "shards" and "indices" (cluster does not make sense here)

Lee Hinman a754224751 Add field data memory circuit breaker.
This adds the field data circuit breaker, which is used to estimate
the amount of memory required to load field data before loading it. It
then raises a CircuitBreakingException if the limit is exceeded.

It is configured with two parameters:

`indices.fielddata.cache.breaker.limit` - the maximum number of bytes
of field data to be loaded before circuit breaking. Defaults to
`indices.fielddata.cache.size` if set, unbounded otherwise.

`indices.fielddata.cache.breaker.overhead` - a contast for all field
data estimations to be multiplied with before aggregation. Defaults to
1.03.

Both settings can be configured dynamically using the cluster update
settings API.

Richard Boulton b62cc7c716 Clean up wording to reduce confusion
The description of the timeout parameter was worded misleadingly; it implied that the API would wait until the cluster reached the desired level and then stayed at that level for the timeout. I've tweaked the sentence to remove the risk of confusion.
