Add more metrics to v3/cluster/erasure-set (#19714)

Browse Source 
Metrics being added:

- read_tolerance: No of drive failures that can be tolerated without
  disrupting read operations
- write_tolerance: No of drive failures that can be tolerated without
  disrupting write operations
- read_health: Health of the erasure set in a pool for read operations
  (1=healthy, 0=unhealthy)
- write_health: Health of the erasure set in a pool for write operations
  (1=healthy, 0=unhealthy)
