ElastAlert query for special characters.

Since below query has special characters, it fails when try to send an alert and error is logged in elastalert_status*

query: “message:high disk watermark [90%]”

To avoid that give like

query: “message: \”high disk watermark [90%]\””

put-records-elasticsearch.yaml: |-
    ---
    name: put-records-elasticsearch
    type: cardinality
    limit_execution: "0/10 * * * *"
    index: eck-logs
    min_cardinality: 50
    cardinality_field: "message"
    timeframe:
      minutes: 15
    filter:
    - query:
        query_string:
            query: "message: \"high disk watermark [90%]\""
    alert:
    - "email"
    email:
    - "sam@sam.com"
    from_addr: "sam@sam.com"
    alert_subject: "Logstash is unable to PUT records in Elasticsearch."
