Reduce request timeout to 10s from 60s

[kirankumarkolli]

This value is used to denote the maximum timeout per network request, rather than the overall request. Cosmos SDK's availability resiliency is heavily reliant on failure detection and retries, both within a partition as well as between regions. However, this requires us to not wait indefinitely (which, honestly, 60 seconds is) for a response from the server, and timeout such network calls and let our retry logic kick in.

Hence.. this change decreases the timeout from 60s to 10s.

Is there/will there be/would you recommend an equivalent adjustment for v2?

[kirankumarkolli]

@bartelink yes there is a V2 follow-up in-flight.

@kirankumarkolli

the default value of ConnectionPolicy.RequestTimeout is surfaced (used) as default value for CosmosClientOptions.RequestTimeout. i'm seeing the doc is not updated (default still says 60s instead of 10s). could someone please update that?
