[BREAKING][BUG] New transport action cluster:monitor/term is preventing authorization for non-wildcard permissions

[peternied]

What is the bug?
A new feature was added into OpenSearch core [1] that performs a lightweight query to see if the cluster metadata needs to be retrieved, or if local metadata can be used. A non-user facing transport action created named as cluster:monitor/term, and unless a user has been granted access any cluster metadata related requests will fail.

How can one reproduce the bug?
./gradlew test --tests org.opensearch.security.DoNotFailOnForbiddenTests.shouldPerformCatIndices_positive

Output

Tests with failures:
 - org.opensearch.security.DoNotFailOnForbiddenTests.shouldPerformCatIndices_positive

What is the expected behavior?
This new action should not need permissions to be performed, it should be renamed to internal:monitor/term

Do you have any additional context?
