feat: Adding zapi/rest templates for lock-get-iter & protocols/locks

[Hardikl]

Adding the zapi template for lock-get-iter.

With these below promQL queries, we can get lock count by volume, vserver, lif, node and cluster level and use them for alerting purpose.

[Hardikl]

Only Node, Lif, Vserver and Volume level aggregated metrics of new_status are exported.
