Support for different node types (data, tribe, http only, ingest (starting from vers. 5))

The elasticsearch setup is nice for small setups. Bigger setups for millions or billions of documents needs a more specific setup like this 10 data node, 2 http only nodes and tribe nodes. Each type has different ressources requirements.
Starting from Version 5 there is a new ingest node type.

Something like a configuration form setup is needed to configure the node types.

I think we should add master nodes as well

[thebennos]

As I know, the master node are automatically selected. do not have a config in mind, where we can set a node to be always a master.
Think the master(s) gets elected by a quorum.

each type of node should have a possibility to customize info about resources. Master node(s) should be separated and without data (storage is not required).
