[Feature Request] Cancellation support for cat/indices API.

[aasom143]

Is your feature request related to a problem? Please describe

Today, the cat indices API does not support overall timeouts or per-node transport request timeouts. In the event of a faulty node, the API can become unresponsive, and in a heavily loaded cluster, the API may take longer than expected to respond. It is essential to implement timeout support for the cat indices API.

Describe the solution you'd like

Recently, we added cancellation support for the cat shards API, which allows us to specify an overall timeout for the API. Additionally, there are some APIs that support a per-node transport request timeout, such as cat/nodes. This enhancement addresses both issues mentioned above.

@aasom143 - Looks like the documentation of /_cat/nodes does not specify the timeout parameter. We might require to fix the same.

Also can we move this under a parent Meta issue for Cancellation and have the potential Admin API's for which cancellation can be implemented.
