result_large_err difficult to suppress selectively

[ijackson]

Description

In my program, I have a StartupError type, which is quite large. This isn't a problem because this is only returned from functions called at startup.

I would like to suppress the result_large_err lint for Result<_, StartupError> but that doesn't seem to be possible. Instead, I have to suppress it globally, since doing so per-function is very obtrusive.

This will probably require adding a configuration option for types that this lint should ignore. But Clippy is in a feature freeze right now, so this will need to wait a bit..
