Disabling Gloo logging regarding ranks

[SKPsanjeevi]

Currently due to this line:

gloo/gloo/transport/tcp/context.cc

Line 243 in 1dbd7e9

std::cout << "[Gloo] Rank " << rank << " is connected to "

, we are getting a bunch of logs/print in a training workload along the following lines:

[Gloo] Rank 5 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 7 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 0 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 1 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 2 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 4 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 3 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 6 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 0 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 1 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 4 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

[Gloo] Rank 2 is connected to 7 peer ranks. Expected number of connected peer ranks is : 7

Is it possible to suppress these logs, say via a flag?
