Utilities for rules that expose resource_set on ctx.actions.run[_shell]
Workaround for https://github.com/bazelbuild/bazel/issues/15187
Note, this workaround only provides some fixed values for either CPU or Memory.
Rule authors who are ALSO the BUILD author might know better, and can
write custom resource_set functions for use within their own repository.
This seems to be the use case that Google engineers imagined.
## resource_set
resource_set(attr)
**PARAMETERS**
| Name | Description | Default Value |
