fix: fix lockup in merge-walk pool (#10098)
Fixes two different types of problems

- continuation of the problem seen in FS #9992
  as not fixed for erasure coded deployments,
  reproduced this issue with spark and its fixed now

- another issue was leaking walk go-routines which
  would lead to high memory usage and crash the system
  this is simply because all the walks which were purged
  at the top limit had leaking end walkers which would
  consume memory endlessly.

Put an upper limit on walk pool sizes (#9848)
Fixes potentially infinite allocations, especially in FS mode, 
since lookups live up to 30 minutes. Limit walk pool sizes to 50 
max parameter entries and 4 concurrent operations with the same
parameters.

Fixes #9835
