[Backport] Add Shard Level Indexing Pressure (#478) to 1.x

[getsaurabh02]

This is backport PR for #478 to 1.x from main

Shard level indexing pressure improves the current Indexing Pressure framework which performs memory accounting at node level and rejects the requests. This takes a step further to have rejections based on the memory accounting at shard level along with other key performance factors like throughput and last successful requests.

Key features

• Granular tracking of indexing tasks performance, at every shard level, for each node role i.e. coordinator, primary and replica.
• Smarter rejections by discarding the requests intended only for problematic index or shard, while still allowing others to continue (fairness in rejection).
• Rejections thresholds governed by combination of configurable parameters (such as memory limits on node) and dynamic parameters (such as latency increase, throughput degradation).
• Node level and shard level indexing pressure statistics exposed through stats api.
• Integration of Indexing pressure stats with Plugins for for metric visibility and auto-tuning in future.
• Control knobs to tune to the key performance thresholds which control rejections, to address any specific requirement or issues.
• Control knobs to run the feature in shadow-mode or enforced-mode. In shadow-mode only internal rejection breakdown metrics will be published while no actual rejections will be performed.
