support a config file

[travi]

i have a few of projects that need to prevent updates for a couple of pinned dependencies. i'm able to do this with updtr if i remember to provide the --exclude flag. the problem, though, is remembering to do that.

it would be great if i could capture config that i need to use repeatedly per project in a way that could be versioned with the project.

i've seen that a number of projects are now using cosmic-config to simplify getting config info into cli-based apps and make it flexible for consumers to decisde where they define their config. personally, i've given up on keeping the root of my projects clear of config files, so i'd be happy to add a .updtrrc to my collection of rc files that already litters all of my projects.

would something along these lines be possible to save us from forgetting to provide config directly on the cli?
