[Feature Request] Support total_primary_shards_per_node limit for segrep indices

[Bukhtawar]

Is your feature request related to a problem? Please describe

The current limit on total_shards_per_node doesn't help in case of segrep since primaries do the actual work and we can run into situations where we have multiple primary on one node and multiple replica on another node causing a skew in resource utilisation and decreased throughput

Describe the solution you'd like

Having a limit on total_primary_shard_per_node will help distribute primary load for segrep indices across all nodes
