`lncli` command `walletbalance` apparently no longer supports the `--witness_only` argument. With the deprecated argument:
```
root@8a9ad8528430:/go/src/github.com/lightningnetwork/lnd# lncli walletbalance --witness_only=true
Incorrect Usage: flag provided but not defined: -witness_only
NAME:
lncli walletbalance - Compute and display the wallet's current balance
USAGE:
lncli walletbalance [arguments...]
[lncli] flag provided but not defined: -witness_only
```
After removing that argument:
```
root@8a9ad8528430:/go/src/github.com/lightningnetwork/lnd# lncli walletbalance
{
"total_balance": "1505000000000",
"confirmed_balance": "1505000000000",
"unconfirmed_balance": "0"
}
```
* Update go version for Docker `lnd` build
Per #815, https://github.com/lightningnetwork/lnd/blob/master/htlcswitch/circuit.go#L21 depends on go version >= 1.9
Before this change:
```
Building lnd
Step 1/11 : FROM golang:1.8
...
Step 9/11 : RUN go install . ./cmd/...
---> Running in 7f5d6ac430e5

htlcswitch/circuit.go:21: syntax error: unexpected = in type declaration
ERROR: Service 'lnd' failed to build: The command '/bin/sh -c go install . ./cmd/...' returned a non-zero code: 2
```
After:
```
