Logstash keystore --stdin option

[nbowditch]

Other Elastic products (Elasticsearch, Kibana) support a --stdin option when adding a key to the keystore. In my specific case, I was trying to pipe a value for the key to the add command, but found that the value would be terminated early at a space in the value.

Example Powershell:

$TestValue = "TEST TEST"
$TestValue | .\bin\logstash-keystore.bat add "test"

Example conf file:

...
filter {
    mutate {
        add_field => { "test" => "${test}" }
    }
}
...

Resulting document:

{
    "test": "TEST",
    ...
}

Version: 6.8.0
Operating System: Windows 10

👋 Logstash team, I think we are hitting this issue in ECK (elastic/cloud-on-k8s#8270), do you know if there is any workaround? Thanks!
