   While debugging: 
   
   - As part of PulsarService start, it fails while reading nic speed 
("/sys/class/net/<nic>/speed") with "java.io.IOException: Invalid argument" 
exception. 
   
   - cat on same nic path fails for me. (my Wifi nic speed do not have specific 
value)

   I believe Pulsar CI Github action is running on VM where nic speed is set 
and test run is able to read nic speed of a VM where test-suite is running. 
This failure can only be observed if test is running on machine/VM where nic 
speed is not set.
   
   Possible fix : 
        
   - Since, The test is asserting on metadata values such as Topic, Tenant, 
Namespace and nothing related to underlying machine resource limits  so, 
setting "loadBalancerOverrideBrokerNicSpeedGbps=2" as part of broker test 
config (standalone_no_client_auth.conf) would fix this.
   
   
   I am new to this project. So, can someone confirm the same? Happy to know if 
I have missed something.
