Use multiple golint tools in the same repo

Is your feature request related to a problem? Please describe.
We have two golangci-lint files in our repo. One is the default one. The other is the "Run this only on new changes (using the --new-from-rev flag)". They have different configurations, and will need different flags to work.

Describe the solution you'd like
I want to be able to configure both of these in my environment, with different flags and configs for each.

Describe alternatives you've considered
Alternative: I created a merged config just for the IDE. Not a great solution since I now need to maintain an extra file.
