Alexander Reelsen d4fcf23057 Cluster State API: Remove index template filtering
The possibility of filtering for index templates in the cluster state API
had been introduced before there was a dedicated index templates API. This
commit removes this support from the cluster state API, as it was not really
clean, requiring you to specify the metadata and the index templates.

Closes #4954

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 24abb6cf3f Cluster state toXContent serialization only returns needed data
In order to make sure, that only the requested data is returned to the client,
a couple of fixes have been applied in the ClusterState.toXContent() method.
Also some tests were added to the yaml test suite
