I'm trying `DisableInitialHostLookup`. Although there are some parts I'm not
sure, it's working fine.

```
On startup, it had 3 connections, including 2 connections to 172.16.1.28,
for some reason. After the error `cannot find host` on the connection to
172.16.1.28, it had 4 connections, including 2 connections to 172.16.1.14 and 1
connection to 127.0.0.1 that was down.
I'm not sure if this is a normal behavior or not, but it's working.
By the way, I came up with another work around. It might be a better
solution to add a HostFilter in cluster config to ignore 127.0.0.1:
```
cluster.HostFilter = gocql.HostFilterFunc(func (h *gocql.HostInfo) bool {
return h.ConnectAddress().String() != "127.0.0.1"
})
```
So far it's working fine after refreshRing, I will keep it for a while
longer.
