Extract metadata using CAT API and store it to OpenSearch

[prashanttct07]

As part of this feature I would like to store below configuration in the monitoring cluster.

1. Domain index details such as number of indices, number of shards, allocations
2. Once data is extracted it should be scheduled to run a daily job to update the data, which should be configurable to make it daily, weekly or bi-weekly
3. Create charts and reports to show index metadata details in centralized dashboards
4. Setup alerts for inconsistencies on index and shards data extracted in step 1.

This will help to view whole stack on this dashboard instead of going back to individual dashboards and running the API on individual cluster. Probably call the CAT API using lambda and send those details to Amazon OpenSearch Service
