Nik Everett 2087234d74 Timeout improvements for rest client and reindex ()
Changes the default socket and connection timeouts for the rest
client from 10 seconds to the more generous 30 seconds.

Defaults reindex-from-remote to those timeouts and make the
timeouts configurable like so:
```
POST _reindex
{
  "source": {
    "remote": {
      "host": "http://otherhost:9200",
      "socket_timeout": "1m",
      "connect_timeout": "10s"
    },
    "index": "source",
    "query": {
      "match": {
        "test": "data"
      }
    }
  },
  "dest": {
    "index": "dest"
  }
}
```
