[BUG] Index management policy ignores index patterns starting with asterisk

[andy812]

I use opendistro with index management plugin v1.13.2.0. My index policy contains such ism_template:

"ism_template": {
        "index_patterns": [
            "prod-*",
            "dev-*",
            "*-events-*"
        ]
}

I have no problems with indices prod-service1-timestamp, prod-service2-timestamp, dev-service1-timestamp, etc. But policy do nothing with indices kube-system-events-timestamp, default-events-timestamp, etc.

How to fix it?

Tested with same ism_template's index_patterns. Create kube-system-events-timestamp index and see it's being managed.

One thing I suspect is when do you create kube-system-events-timestamp? If it's created before ism_template is there, it won't be auto managed.
