Tune http logs workload params for remote store nightly runs

[ashking94]

Description

This tunes the workload params that are passed during the nightly perf runs for http logs workload for the nighly runs. Summary of the changes -

• remote translog buffer interval changed to 250 ms : This interval is time for which the translog upload is buffered and performed periodically.
• refresh interval 10s : We propose to increase the refresh interval to higher number since a round of segment replication using remote store requires certain duration. With 10s, a user would be certain to have the docs refreshed on replica as well.
• bulk indexing client doubled - This has been done to allow more number of calls to be made to remote store enabled cluster. A remote enabled index gives request level durability to the user by acknowledging a write request only after it has been persisted durably on remote store. With it, it also leads to higher latency for workloads which have very low end to end latency (150-200ms was the p50 during the OSB runs that I observed). This leads to lesser throughput as the cluster is not getting exposed to enough concurrency and stays much below in terms of cpu in comparison to segrep or docrep run clusters.
• bulk size changed to 20K - this allows the remote upload buffering to be more optimal.
