[IMPROVEMENT] Reduce calls to /_all/_alias/{aliases}

[Xtansia]

Is your feature request related to a problem?

The connector always makes a call to /_all/_alias/{resouce_name} on every read or write task attempt to determine if the provided resource name is actually an index name or is an alias.
This causes deprecation logging on the OS server side as _all will match system indices.

What solution would you like?

Options:

• Add in-memory caching of results, based on time period, to reduce frequency of calls.
• Improve API usage to avoid matching system indices.
• Allow forcing index treatment via setting, not helpful for case where resource is an alias
