Use standard error wrapping/unwrapping instead. The conversion is mostly
straightforward, but see grpc/grpc-go#2934 for GRPC `status.FromError`, it
doesn't currently support unwrapping/errors.As(), so we're unwrapping manually
here.
Current scheme requires people to calculate exact percentages for their
nodes. People are bad with pecentage calculations and it's really inconvenient
if you have more than 3-4 nodes. What I'd like to have is ability to specify
weights like weights, not percentages:
.._0_WEIGHT=3
.._1_WEIGHT=1
.._2_WEIGHT=1
and let the gateway calculate things for me.
