Thanks @panslava -- Please double check that besides the timeout flag, we aren't removing any other flags (atleast I didn't spot any but worth checking). For timeout, I tried to verify that it isn't being used elsewhere in the binary invocation so hopefully we should be all good with removing it.

@gauravkghildiyal I rebased on master could you please lgtm again

I checked again, I don't think we remove any other flags than serverTimeout

/unhold
