gnzlbg c79f39af16 Add integration tests against crates in the rust-lang-nursery
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.

# FIXME: this is causing the build to fail when rustfmt is found in .cargo/bin
# but cargo-fmt is not found.
#
# `which rustfmt` fails if rustfmt is not found. Since we don't install
# `rustfmt` via `rustup`, this is the case unless we manually install it. Once
# that happens, `cargo install --force` will be called, which installs
# `rustfmt`, `cargo-fmt`, etc to `~/.cargo/bin`. This directory is cached by
# travis (see `.travis.yml`'s "cache" key), such that build-bots that arrive
# here after the first installation will find `rustfmt` and won't need to build
# it again.
#
# which rustfmt || cargo install --force
cargo install --force
