mysql: unknown auth plugin

[mrjones-plip]

If I use the default customer-db value in dnsauth.toml:

customer-db = "root:pass@(127.0.0.1)/customers"

Everything works fine. But if I use a custom one like this:

customer-db = "user:password@(192.168.68.42)/dns_query"

I get an error:

2018/06/14 19:50:37 [CustomerDB] Refreshing list from mysql...
[mysql] 2018/06/14 19:50:37 auth.go:293: unknown auth plugin:
[mysql] 2018/06/14 19:50:37 driver.go:120: could not use requested auth plugin '': this authentication plugin is not supported

The .42 IP is my mysql server with the zones table in the dns_query DB. The table is very large (80k+ rows).

I tested with different user name and passwords and database names and got the correct errors (bad auth & table not found), so it is connecting OK. Maybe it's still working? I'll test ingestion next, but we should resolve the error all the same.

oh! it might be helpful to know that even with an authentication error, the unknown auth plugin error hits regardless:

It looks like this doesn't prevent ingestion, but I'm not sure if this affects #9 or not.
