Add issue templates for bugs and features (#152)

I would love feedback on how people feel about these issue templates, if
there should be more or less templates, or if there are any fields that
people think we should add.

You can see an example of how to use these by testing opening an issue
on my fork [here](https://github.com/katiewasnothere/container/issues).
