[FEATURE REQUEST] ISM template index pattern support excluding operator -

[pytomtoto]

Describe the bug I have a index pattern *,-code* to include all index and exclude "code*"

when I use this index pattern to ILM . I Found it's not work.

    "ism_template": [
        {
            "index_patterns": [
                "*",
                "-code*"
            ],
            "priority": 100,
            "last_updated_time": 1623292398930
        }
    ]

ILM Policy always include all index。

Hi @pytomtoto ,

Probably this is a feature request for Index Management plugin. In their user guide (https://opensearch.org/docs/latest/im-plugin/ism/policies/), it's not mentioned that "index_patterns" supports excluding targets with the syntax -. I will ask the team to transfer the issue to index-managment repository to let the developers there give a better answer.

ISM doesn't support - pattern to exclude sth. This can be a feature request.
