Allow local database sanitization to be disabled

[geerlingguy]

My system information:

• Operating system type: macOS
• Operating system version: 10.12.2
• BLT version: 8.6.6

When I run this command:

blt local:refresh

I get the following result:

The database is always sanitized locally, meaning users can't login with their prod username/password combos (everyone is forced to use drush @site.local uli username to log in).

And I wanted this to happen:

I would like a way to disable the local database sanitization, so if we deem it secure enough to not sanitize local database copies, we can choose that option.

Can sanitization be turned off globally?
