Change to reproduce the delay in creating the control storage layout

[raj-prince]

Command to run: time go run . --bucket <bucket_name> --client-protocol control
Output looks like:

time go run . --bucket tail-latency-test-bucket-multi-regional-us --client-protocol control
Time taken (second) in storageLayoutFetch:  10.077479734
Time taken (second) in namespace fetch:  1.21e-07
enabled:true

real    0m11.113s
user    0m2.371s
sys     0m1.095s

As we can see, clearly storageLayout fetch is taking around 10s.
