Can't run `cargo test --all` for `error-chain` anymore. The tests don't
compile because of `#[deny(invalid_doc_attributes)]`. Here's the error
message:
```
error: this attribute can only be applied at the crate level

The `cargo test --all` command failed and exited the main process with a
SIGINT. Trapping the signal or trying to get the code of a subshell
didn't work.
Close#2724
This commit adds integration tests against some crates in the
nursery.
Each integration test is added as a separate build-bot, where
the rust-lang-nursery/${CRATE} is first downloaded and its tests run.
Afterwards, `cargo fmt --all` is applied to the crate, and the tests
are re-run. If the tests fail after formatting, the integration test
fails.
The crates that currently fail are added as allowed-to-fail, but the
intent is that either these crates or rustfmt should be fixed such
that the tests pass.
