Handle and parse error

[saynb]

Only the top level error is handled today. We need a way to be able to parse the individual update errors in a batch

@antoninbas Any insight on this ?

That sounds like the right thing to do.
At the moment, we call the Write RPC and return the error from the gRPC as is:

p4runtime-go-client/pkg/client/client.go

Lines 146 to 147 in 0c0dbfb

	_, err := c.Write(ctx, req)
	return err

We should probably extract the inner errors and return a custom Golang error type which is more user-friendly.
Feel free to take a stab at this if you have some cycles.
