[FEATURE] Tool development for search AD result Tool

[ylwu-amzn]

Is your feature request related to a problem?

Agent framework (#1161 ) needs tools to extend functionality. This issue propose to add search AD result tools to it.

What solution would you like?

Build a tool in AD plugin to search AD result.

Agent framework (#1161 ) will provide a general tool framework. We can build search monitor/alerts tools with that framework.

1. Build against the Tool interface on the agent_framework_dev branch: https://github.com/opensearch-project/ml-commons/blob/feature/agent_framework_dev/spi/src/main/java/org/opensearch/ml/common/spi/tools/Tool.java

2. Review example tools in the Agent Framework POC commit: 1b85cff where there are 6 tools under ml-algorithms/src/main/java/org/opensearch/ml/engine/tools/. A good example is the CatIndices tool: https://github.com/opensearch-project/ml-commons/blob/feature/agent_framework_dev/ml-algorithms/src/main/java/org/opensearch/ml/engine/tools/CatIndexTool.java which shows how to use the NodeClient (IndicesAdminClient) to fetch Cluster Health statistics.

What alternatives have you considered?
N/A

Do you have any additional context?

Combining this issue with search anomaly detectors tool. The current implementation will be using an exposed AD client (see here), and then instantiating it within ML commons to execute AD transport actions within ML commons plugin.
