vendor: bump google.golang.org/grpc v1.23.1

full diff: grpc/grpc-go@v1.23.0...v1.23.1

- grpc/grpc-go#3018 server: set and advertise max frame size of 16KB
- grpc/grpc-go#3017 grpclb: fix deadlock in grpclb connection cache
    - Before the fix, if the timer to remove a SubConn fires at the
      same time NewSubConn cancels the timer, it caused a mutex leak
      and deadlock.
