Removed duplicate dependencies of examples in the top level workspace (#407)
This PR adds `rust_workspace` which is meant to define transitive dependencies as well as cleans up some duplicate files that were in the root of the project but only used by examples.
## Updated documentation
Note the updated documentation in [docs/index.md](https://github.com/UebelAndre/rules_rust/blob/workspace-structure/docs/index.md)
## Added `bazel_skylib` to `rust_repositories`
It appears there are some uses of `bazel_skylib` within these rules but there aren't really any guarantees that that repository is available. This may be my fault with the changes made in #399 to [@io_bazel_rules_rust//rust/platform:platform.bzl](https://github.com/bazelbuild/rules_rust/blob/master/rust/platform/platform.bzl#L3) but I feel the `bazel_skylib` dependency should be conditionally added
## Added `rust_workspace`
I feel this is much nicer on the users's end as it gives them a single place to go to look at dependencies and is nicer on the repo because it means dependencies can more easily updated. I'm not the biggest fan of the name `rust_workspace` so if this was an acceptable concept, I'm happy to take suggestions on what the name should be called.
