Better ES settings on docker-compose

[humitos]

• Disable check for allocation which is not needed on development
• Set a better name to the node

This avoid the cluster going read-only mode because not "enough" space on disk,

search_1     | [2019-12-05T16:38:02,390][WARN ][o.e.c.r.a.DiskThresholdMonitor] [1qOjoH7] flood stage disk watermark [95%] exceeded on [1qOjoH7qRX2hXuMCo80xOg][1qOjoH7][/usr/share/elasticsearch/data/nodes/0] free: 4.2gb[4.7%], all indices on this node will be marked read-only

If you are already experimenting this problem, this command makes the index to be non read-only again (execute from web container):

curl -H'Content-Type: application/json' -XPUT search:9200/_all/_settings?pretty -d'
{
    "index": {
        "blocks.read_only": false
    }
}'
